31 This, a second letter, beloved, I already write to you, in [both] which I stir up, in the way of putting you in remembrance, your pure mind, 2 to be mindful of the words spoken before by the holy prophets, and of the commandment of the Lord and Saviour by your apostles;
3 knowing this first, that there shall come at [the] close of the days mockers with mocking, walking according to their own lusts, 4 and saying, Where is the promise of his coming? for from the time the fathers fell asleep all things remain thus from [the] beginning of [the] creation.
Matthew Henry's Commentary on 2 Peter 3:1-4
Commentary on 2 Peter 3:1-4
(Read 2 Peter 3:1-4)
The purified minds of Christians are to be stirred up, that they may be active and lively in the work of holiness. There will be scoffers in the last days, under the gospel, men who make light of sin, and mock at salvation by Jesus Christ. One very principal article of our faith refers to what only has a promise to rest upon, and scoffers will attack it till our Lord is come. They will not believe that he will come. Because they see no changes, therefore they fear not God, Psalm 55:19. What he never has done, they fancy he never can do, or never will do.
