Scoffers and scorners are people filled with negativity. God has warned us that in the last days, self-righteous people will challenge believers about His promised return.
“Knowing this first: that scoffers will come in the last days, walking according to their own lusts, and saying, ‘Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of creation'” (2 Peter 3-4).
No Christian should be a scoffer or a scorner. It is a bad testimony to the lost and it will cause believers to stumble. We must always be careful to not do anything that will tarnish our image among the lost (1 Peter 2.12), and cause brothers in the Lord to stumble (Romans 14.13, 21).
When you encounter a scoffer the best thing to do is move on and let him go his scornful way. It never pays to argue with a scoffer or scorner for they are fools (Proverbs 29.9).
