The Covenant of Grace

The covenant of grace is the eternal arrangement by which God saves sinners through Jesus Christ apart from their own merit. It stands in contrast to the covenant of works made with Adam, in which life depended on perfect personal obedience. The doctrine matters because it determines whether salvation rests on human performance or on God's free promise, and it shapes how believers understand assurance, obedience, and the unity of the Bible's story. Spurgeon, Edwards, and Henry all treat this covenant as the heartbeat of the gospel, though they emphasize different facets of its structure and application.

The eternal foundation of the covenant

Spurgeon stresses that the covenant of grace did not begin after the fall but was arranged in eternity. He says that God the Father consented to the arrangement in which Christ would suffer the sinner's punishment and be accounted guilty in the sinner's place (Romans 3:24). Christ was appointed as the propitiation from eternity, before the world was made or Adam fell (Romans 3:25). This means the cross was not an emergency measure but the unfolding of a plan older than creation. Edwards agrees, arguing that Christ was under no prior obligation to obey or suffer for himself; both his obedience and suffering were undertaken in an eternal transaction with the Father as our surety. God justified and saved sinners on the ground of Christ's future obedience and suffering before those things were actually performed. Spurgeon adds that Jesus did not die to make the Father gracious; rather, His death flows from the Father's eternal love and the eternal covenant of grace (Romans 4:25).

Henry brings the Old Testament into view by noting that the gospel is not a new doctrine but was promised beforehand in the Old Testament Scriptures (Romans 1:2). The sins of Old Testament saints were pardoned for the sake of the atonement Christ would make in the fullness of time, which looked backward as well as forward (Romans 3:25). Spurgeon makes the same point when he says God set forth Christ as the propitiation throughout the Old Testament through verbal promises, types, and symbols (Romans 3:25). The covenant therefore has one Savior and one ground of acceptance from Genesis to Revelation.

The promise to Abraham and its seed

All three authors treat Abraham as the great pattern of covenant faith. Spurgeon says Abraham's faith looked to the promised Messiah, Jesus Christ, as the central point of the covenant promise (Romans 4:17). Abraham's blessing came by faith and grace, not by his own merit, as shown by God's sovereign call, covenant, and the promised child born according to promise (Romans 4:16). Henry explains that circumcision was given as a seal of the righteousness Abraham already had by faith, confirming a previously established covenant (Romans 4:11). Sacraments in general are signs to represent and instruct, and seals to ratify and confirm; they are mutual seals between God and his people (Romans 4:11). Henry draws a direct implication for the church: since infants then received this seal, infant baptism under the gospel should not be rejected (Romans 4:11).

Edwards focuses on the legal and federal structure of the promise. He argues that the law given four hundred and thirty years after Abraham was not a new law beginning to exist then, but the solemn giving of the moral law, especially the Ten Commandments, at Mount Sinai (Galatians 3:17). Paul's argument is that God would not disannul the covenant of grace made with Abraham by later establishing a covenant of works at Mount Sinai (Galatians 3:17). Henry agrees that the promise to Abraham was made before the law was given, so inheritance does not come through the law (Romans 4:13–16). The promise was made through faith so that it might be sure, because a covenant of works would fail through human frailty, but faith depends continually on Christ who keeps our salvation safe (Romans 4:16).

Spurgeon adds that salvation by faith rather than law was necessary so that Gentiles, who were never under the Law of Moses, could be included in the promise to Abraham's seed (Romans 4:16). Henry makes the same point: the promise was made through faith so that it might extend to all the seed, both Jews and Gentiles, not limited to those who had the law (Romans 4:16). Abraham is the father of all believers because he is the great pattern of faith and justification, not merely the physical ancestor of the Jews (Romans 4:11–12). Spurgeon states that Abraham is the father of all believers, whether circumcised or not, and the promises made to him belong to them also (Romans 4:16).

Grace excludes boasting and merit

Spurgeon is emphatic that the covenant of grace admits no human work and therefore admits no boasting at all (Romans 3:27). A reward received by merit would feel unsafe because the title to it would not be sound (Romans 5:21). Faith never borrows from the law or pleads as though God owed a debt, but always holds to the promise of the gracious God (Romans 4:16). He warns that basing eternal differences in glory on human devotion would reintroduce salvation by works, which is contrary to the covenant of grace (Romans 3:27, Galatians 4:30).

Edwards frames the same truth in terms of the purpose of justification. The way of justification appointed in the gospel covenant was appointed for the purpose of expressing and glorifying free grace (Romans 4:16). The covenant of grace differs from the covenant of works because justification is by faith in Jesus Christ, not by our own works (Romans 4:16, Romans 3:20, Romans 3:24, Romans 11:6, Galatians 5:4). He insists that the doctrine of justification by faith is of great importance because it is the chief difference between the covenant of grace and the first covenant. The difference between justification by Christ's righteousness and justification by human virtue is fundamental, not a minor point. The essential difference between the covenant of grace and the covenant of works is found in this doctrine of justification.

Henry adds a pastoral dimension. Being under grace rather than law is a strong motive against sinning, because grace accepts the willing mind, leaves room for repentance, and promises pardon upon repentance (Romans 6:14). Yet he also warns that it is a shameful abuse of grace to use it as an excuse to sin, and the apostle strongly rejects such a thought (Romans 6:15). The covenant of grace provides strength to obey and keeps salvation secure in the hands of Christ the Mediator, unlike the covenant of works which demands perfect obedience and condemns every failure (Romans 6:14).

Christ as surety and second Adam

Edwards develops the federal headship of Christ more fully than the others. Christ is the second federal head who acted for us as the first Adam should have done, bearing our guilt and then providing the positive obedience required for eternal life (1 Corinthians 15:22). As covenant surety, Christ not only provides righteousness for his people but also secures their voluntary, penitent, believing obedience by divine influence from himself. Heaven is a purchased possession, not something acquired by our own obedience after Christ merely removes the penalty of sin (Ephesians 1:14).

Spurgeon agrees that Christ's headship over His people qualified Him to suffer in their place, just as Adam's headship caused their fall (Romans 4:25). Henry explains that Adam was a type or figure of Christ, the second Adam, who communicates righteousness and life in parallel to how Adam communicated sin and death (Romans 5:12–21). Adam was a type of Christ because both acted as public persons, representing others before God (Romans 5:14). Adam was a figure of Christ who was to come to repair the breach Adam had made (Romans 5:14).

Edwards also addresses the relationship between faith and obedience in Abraham's life. Abraham's justifying faith was not his first act of faith, but a later act exercised long after he had already believed and obeyed God (Galatians 3:6, Hebrews 11:8). Abraham received in reward for his obedience the very blessings that had already been absolutely promised to him by faith (Genesis 22:16–18, Genesis 12:2–3, Genesis 13:16, Genesis 15:1, Genesis 15:4–7, Genesis 17:1–27, Genesis 18:10, Genesis 18:18). This shows that covenant blessings are not earned by obedience but are given by promise and then enjoyed in the path of obedience. God's reward of believers' holiness differs from what it would have been under the original covenant, because their works are accepted only as they are viewed in Christ, not as their own independent excellence. Under the covenant of works the person was accepted for the work's sake, but under the covenant of grace the work is accepted and rewarded only for the person's sake as a member of Christ clothed with his righteousness.

The certainty of the covenant promises

Spurgeon grounds assurance in the character of God and the blood of Christ. The throne of grace is secured by the blood of Christ and by God's unbreakable oath and promise (Romans 5:21). God's honor is bound to the fulfillment of His covenant promises, so believers can speak with certainty of their justification and peace with God (Romans 5:1). Salvation by grace through faith rests on the sure foundation of God's decree, covenant promise, and the blood of Christ, making it eternally secure (Romans 4:16). A believer's right to God's promises rests on being united to Christ, not on whether a promise has been fulfilled or personally applied (Romans 3:25).

Henry agrees that God's word, especially his promise, never fails or becomes ineffective, even when circumstances make its fulfillment seem doubtful (Romans 9:6). God being for believers sums up all their privileges, meaning he is reconciled to them, in covenant with them, and engaged for them with all his attributes and promises (Romans 8:31). The promise to Abraham was never intended for all his physical descendants, but only for a specific chosen line, so the rejection of some Jews does not break God's promise (Romans 9:6–13). God's covenant promise to Abraham did not fail even though Ishmael was rejected, because God as the giver of the blessings was free to choose which of Abraham's descendants would receive them (Romans 9:6–7).

Spurgeon addresses the apparent problem of Jewish unbelief directly. The unbelief of some Jews did not nullify God's covenant promises or His faithfulness (Romans 3:3). God did not fail to keep His promise to Israel even though many Israelites died in unbelief, for He brought the nation into the Promised Land and continues to keep His covenant with them (Romans 3:3). God has not cast away His people Israel nor broken His covenant with Abraham, and a day is coming when the remnant of Israel will be gathered in (Romans 3:3–4). Henry adds that the Jews are beloved for the sake of the patriarchs, and God's ancient covenant kindness to the fathers will be remembered in due time (Romans 11:28). God's gracious intentions toward Israel were made the matter of a covenant, and God cannot be unfaithful to his covenant (Romans 11:27).

The covenant and the law

Henry gives the most detailed account of the relationship between the covenant of grace and the law of Moses. In point of profession and privilege, believers are under a covenant of grace and the gospel of Christ, not under a covenant of works and the law of Moses (Romans 7:1–6). The apostle illustrates the difference between a law-state and a gospel-state by the similitude of being married to a new husband, just as he earlier used the similitudes of rising to a new life and serving a new master (Romans 7:1–6). Believers are dead to the law, meaning the law's obligation to punish and provoke sin has lost its power over them (Romans 7:4). The covenant of grace in Christ frees believers from both the guilt and the ruling power of sin (Romans 8:2).

Henry is careful to say that the law given at Sinai, though not a pure covenant of works, contained much of the strictness and terror of the covenant of works in order to drive people to Christ and make the covenant of grace welcome (Romans 10:5). The old covenant brought a spirit of bondage and fear because of its darkness and terror, but believers are no longer under that dispensation (Romans 8:15). Christ has finished the work by ending the types and ceremonies of the Old Testament, and the gospel covenant is cut short and abridged compared to the long train of Old Testament institutions (Romans 9:28). Under the gospel, our duty is summed up in much less room than under the law, and though the covenant is contracted, it remains clear, plain, and easier (Romans 9:28).

Spurgeon highlights a distinctive feature of the covenant of grace: what is commanded in one Scripture is given as a covenant promise in another, namely that God will put his fear in his people's hearts so that they will not depart from him (Romans 3:27). This means the covenant does not merely demand obedience but supplies it. Henry agrees that sin may trouble a believer but cannot rule over him, because believers are under the covenant of grace, not the covenant of works (Romans 6:14). Christ rules believers by grace and will not allow sin to dominate those who willingly submit to his rule (Romans 6:14).

The covenant community and its future

Henry develops the corporate dimension of the covenant more than Spurgeon or Edwards. The olive tree represents the visible church, and Abraham is its root of administration, being the first with whom the covenant was solemnly made (Romans 11:17). Believing Gentiles share in the same covenant privileges as the Jews, including special protection, the oracles of God, means of salvation, a standing ministry, instituted ordinances, and visible church membership for their infant seed (Romans 11:17). Gentile believers are still branches borne by the root of Abraham's covenant and are obliged to it, not the root to them (Romans 11:18, Romans 11:24). The patriarchs were set apart in covenant with God, and this federal holiness gives reason to hope that God will not totally and finally cast off their descendants (Romans 11:16). The seed of believers are within the visible church and covenant by relative privilege, even though saving grace itself is not inherited (Romans 11:16).

Henry also notes that the Jews possessed great privileges as Israelites: the adoption as God's people, the glory, the covenants, the giving of the law, the worship of God, and the promises (Romans 9:4–5). The covenants made with Abraham and renewed with his descendants at Sinai, Moab, Shechem, and afterward belonged to Israel as a great privilege (Romans 9:4). The promises, especially those relating to the Messiah and the gospel state, accompanied the law and the service of God, and their comfort is enjoyed through obedience and attendance on that service (Romans 9:4).

Spurgeon and Henry both look forward to the full ingathering of Israel. Henry says the rejection of the Jews and the inclusion of the Gentiles were foretold in the Old Testament, so they are consistent with God's promises to the fathers (Romans 9:25–29). God can abandon many physical descendants of Abraham to ruin while still keeping his promise to Abraham, because only a remnant will be saved (Romans 9:27). The promise to Abraham included a vast number of descendants, yet only a remnant would be saved, showing that many are called but few are chosen (Romans 9:27). Pardon of sin is the foundation of all the blessings of the new covenant (Romans 11:27). Christ received us into his fold, family, and covenant, even though we were strangers, enemies, and prodigals (Romans 15:7). Christ ministered to the Jews in order to fulfill God's promises to the patriarchs, not because the Jews deserved it (Romans 15:8). The promises made to the fathers were confirmed by Christ's coming as a minister of the circumcision, since in him all God's promises are fulfilled (Romans 15:8). Christ confirmed the covenant of grace by shedding the blood of the covenant (Romans 15:8).

Henry concludes with the note that during the Old Testament era, the mystery of the gospel was only dimly revealed through types, shadows, and dark predictions (Romans 16:25). The victory over Satan will be complete, fulfilling the first promise in Genesis that the seed of the woman would crush the serpent's head (Romans 16:20). In thanksgiving, we should view God as our covenant God, which makes every mercy sweet (Romans 1:8).
