2-peter 3:3

Knowing this first - Considering this in an especial manner, that those prophets predicted the coming of false teachers: and their being now in the Church proved how clearly they were known to God, and showed the Christians at Pontus the necessity of having no intercourse or connection with them.

There shall come - scoffers - Persons who shall endeavor to turn all religion into ridicule, as this is the most likely way to depreciate truth in the sight of the giddy multitude. The scoffers, having no solid argument to produce against revelation, endeavor to make a scaramouch of some parts; and then affect to laugh at it, and get superficial thinkers to laugh with them.

Walking after their own lusts - Here is the true source of all infidelity. The Gospel of Jesus is pure and holy, and requires a holy heart and holy life. They wish to follow their own lusts, and consequently cannot brook the restraints of the Gospel: therefore they labor to prove that it is not true, that they may get rid of its injunctions, and at last succeed in persuading themselves that it is a forgery; and then throw the reins on the neck of their evil propensities. Thus their opposition to revealed truth began and ended in their own lusts.

There is a remarkable addition here in almost every MS. and version of note: There shall come in the last days, In Mockery, εν εμπαιγμονῃ, scoffers walking after their own lusts. This is the reading of ABC, eleven others, both the Syriac, all the Arabic, Coptic, Ethiopic, Vulgate, and several of the fathers. They come in mockery; this is their spirit and temper; they have no desire to find out truth; they take up the Bible merely with the design of turning it into ridicule. This reading Griesbach has received into the text.

The last days - Probably refer to the conclusion of the Jewish polity, which was then at hand.

Knowing this first - As among the first and most important things to be attended to - as one of the predictions which demand your special regard. Jude Jde 1:18 says that the fact that there would be "mockers in the last time," had been particularly foretold by thom. It is probable that Peter refers to the same thing, and we may suppose that this was so well understood by all the apostles that they made it a common subject of preaching.

That there shall come in the last days - In the last dispensation; in the period during which the affairs of the world shall be wound up. The apostle does not say that that was the last time in the sense that the world was about to come to an end; nor is it implied that the period called "the last day" might not be a very long period, longer in fact than either of the previous periods of the world. He says that during that period it had been predicted there would arise those whom he here calls "scoffers." On the meaning of the phrase "in the last days," as used in the Scriptures, see the Acts 2:17 note; Hebrews 1:2 note; Isaiah 2:2 note.

Scoffers - In Jude Jde 1:18 the same Greek word is rendered "mockers." The word means those who deride, reproach, ridicule. There is usually in the word the idea of contempt or malignity toward an object. Here the sense seems to be that they would treat with derision or contempt the predictions respecting the advent of the Saviour, and the end of the world. It would appear probable that there was a particular or definite class of men referred to; a class who would hold special opinions, and who would urge plausible objections against the fulfillment of the predictions respecting the end of the world, and the second coming of the Saviour - for those are the points to which Peter particularly refers. It scarcely required inspiration to foresee that there would be "scoffers" in the general sense of the term - for they have so abounded in every age, that no one would hazard much in saying that they would be found at any particular time; but the eye of the apostle is evidently on a particular class of people, the special form of whose reproaches would be the ridicule of the doctrines that the Lord Jesus would return; that there would be a day of judgment; that the world would be consumed by fire, etc. Tillotson explains this of the Carpocratians, a large sect of the Gnostics, who denied the resurrection of the dead, and the future judgment.

Walking after their own lusts - Living in the free indulgence of their sensual appetites. See the notes at 2 Peter 2:10, 2 Peter 2:12, 2 Peter 2:14, 2 Peter 2:18-19.
