Matthew Henry - Commentary on the Whole Bible
That the apostle might the better reach his end in writing this epistle, which is to make them steady and constant in a fiducial and practical remembrance of the doctrine of the gospel, he, 1. Expresses his special affection and tenderness for them, by calling them beloved, hereby evidencing that he added to godliness brotherly-kindness, as he had (ch. i. 17) exhorted them to do. Ministers must be examples of love and affection, as well as life and conversation. 2. He evinces a sincere love to them, and hearty concern for them, by writing the same thing to them, though in other words. It being safe for them, it shall not be grievous to him to write upon the same subject, and pursue the same design, by those methods which are most likely to succeed. 3. The better to recommend the matter, he tells them that what he would have them to remember are, (1.) The words spoken by the holy prophets, who were divinely inspired, both enlightened and sanctified by the Holy Ghost; and, seeing these persons’ minds were purified by the sanctifying operation of the same Spirit, they were the better disposed to receive and retain what came from God by the holy prophets. (2.) The commandments of the apostles of the Lord and Saviour; and therefore the disciples and servants of Christ ought to regard what those who are sent by him have declared unto them to be the will of their Lord. What God has spoken by the prophets of the Old Testament, and Christ has commanded by the apostles of the New, cannot but demand and deserve to be frequently remembered; and those who meditate on these things will feel the quickening virtues thereof. It is by these things the pure minds of Christians are to be stirred up, that they may be active and lively in the work of holiness, and zealous and unwearied in the way to heaven.
John Calvin - Commentaries
Lest they should be wearied with the Second Epistle as though the first was sufficient, he says that it was not written in vain, because they stood in need of being often stirred up. To make this more evident, he shews that they could not be beyond danger, except they were well fortified, because they would have to contend with desperate men, who would not only corrupt the purity of the faith, by false opinions, but do what they could to subvert entirely the whole faith.
By saying, I stir up your pure mind, he means the same as though he had said, “I wish to awaken you to a sincerity of mind.” And the words ought to be thus explained, “I stir up your mind that it may be pure and bright.” For the meaning is, that the minds of the godly become dim, and as it were contract rust, when admonitions cease. But we also hence learn, that men even endued with learning, become, in a manner, drowsy, except they are stirred up by constant warnings. 175175 The Apostle evidently admits that they had a sincere or a pure mind, that is, freed from the pollutions referred to in the last chapter; but still they stood in need of being stirred up by admonitions: hence their minds were not, in a strict sense, perfect, though sincere. — Ed.
It now appears what is the use of admonitions, and how necessary they are; for the sloth of the flesh smothers the truth once received, and renders it inefficient, except the goads of warnings come to its aid. It is not then enough, that men should be taught to know what they ought to be, but there is need of godly teachers, to do this second part, deeply to impress the truth on the memory of their hearers. And as men are, by nature, for the most part, fond of novelty and thus inclined to be fastidious, it is useful for us to bear in mind what Peter says, so that we may not only willingly suffer ourselves to be admonished by others, but that every one may also exercise himself in calling to mind continually the truth, so that our minds may become resplendent with the pure and clear knowledge of it.
