He who separates himself seeks his own desire, He quarrels against all sound wisdom. Proverbs 18:1
Normally, when a believer separates himself from friends or a community that would hold him accountable it is for the purpose to do his own thing or to sin. This is a very dangerous position for a believer to be in because doing one’s own thing leads to pride, and it also leads to foolishness.
According to the Bible, it is the fool who has said in his heart that there is no God. In other words, the fool believes in his heart that he can do whatever it is that he wants to do without God holding him accountable for it. He has no earthly reminders of accountability because he has separated himself. The person who allows themselves to become a fool will have a rude awakening to God’s judgment. It is foolish to allow ourselves to get to that point.
