"This is now, beloved, the second epistle that I write unto you; and in both of them I stir up your sincere mind by putting you in remembrance; that ye should remember the words which were spoken before by the holy prophets, and the commandment of the Lord and Saviour through your apostles; knowing this first, that in the last days mockers shall come with mockery, walking after their own lusts, and saying, Where is the promise of His coming? for, from the day that the fathers fell asleep, all things continue as they were from the beginning of the creation."--2 PETER iii. 1-4.
In the previous chapter the Apostle showed how the renegade false teachers had published among the brethren their seductive doctrine, declaring that God's fatherly discipline was something which they need not undergo, that the trials which He sent them might be escaped, and the natural bent of man's heart indulged as fully as they pleased. The foul results of such lessons both to the flock and to the teachers he also depicted in such wise as to render them abhorrent. Now he tells of a further lesson which these guides on the downward road added to the former. Those who do not accept God's judgements here soon go on to deny the coming of judgement hereafter. It could hardly be otherwise. The wish is father to the thought as truly in matters of faith as of practice. Men whose lives are all centred on this world must try and convince themselves, if possible, that the day of the Lord, of which God's word speaks so often, is a delusion, and may be cast out of their thoughts. This these men did, and it is against this scoffing of theirs that St. Peter directs his exhortation in this chapter.
_This is now, beloved, the second epistle that I write unto you._ Judging from the adverb which he uses (ἤδη, now, already), we should conclude that no long time had elapsed between the Apostle's first letter and the second. And by calling this the second, he shows that it is intended for the same congregations as the former, though he has not named them in the salutation with which the letter opens. Aforetime they had been tried by inward questionings, and he sent them his exhortation and testimony that, spite of all their trials, this was the true grace of God which they had received, and therein they should stand fast (1 Peter v. 12). Now the danger is from without: false doctrine and evil living as its consequence. So, though he may have written but a little while ago, he will neither spare himself, nor neglect them. For the danger is of the utmost gravity. It threatens the overthrow of all true Christian life.
_And in both of them I stir up your sincere mind by putting you in remembrance._ Mark how trustfully he appeals to the sincerity of the minds of the brethren, just as before (i. 12) he said they knew the things of which he was putting them in remembrance, and were established in the truth which they had received. And what he means by the "mind" we may see from 1 Peter i. 13, where he uses the same word: "Gird up the loins of your mind"--do not indulge vain, lax, and speculative opinions, as though these would forward you in your travel through the world--"be sober, and set your hope perfectly on the grace that is to be brought unto you." A mind so braced looks onward to the revelation of Jesus Christ, looks for every token of its drawing nigh. And because it is sincere, the man dare look into its inmost recesses, and by self-examination and discipline maintain its purity. He can think soberly of the Lord's coming because he is preparing for it. But he whose mind is dark, within whom the light has been turned into darkness, dare not think on these things, but with all his might endeavours to forget, ignore, and deny them. All that St. Peter thinks needful for these Asian brethren is that he should remind them. He knows that men's minds are prone to slumber, especially about the things unseen as yet; and his aim is to rouse them to thorough vigilance. But he has no new lesson to give them.
