What does 2 Peter 3:3 mean?
Jesus himself had warned that false prophets would come and lead many away from the truth (Matthew 24:11). Paul also tied the work of these false teachers to the last days before the return of the Christ (1 Timothy 4:1–3). The New Testament is consistent in describing our era as the last days or end times before Christ returns and is revealed as Lord.Christians are not defenseless against these false teachers. Peter describes two more things that are true of them: They are scoffers (mocking the return of Christ), and they follow their own evil desires. That is, as Peter wrote in chapter 2, they openly engage in immorality and encourage the Christians to join in with them.
In the next verse, Peter will describe how these false teachers will mock the second coming of Jesus. But first, Peter reminds us that the very existence of these false teachers is a fulfillment of prophecy. Their mocking and scoffing was one of the predictions he mentioned in verse 2.
