(Proverbs 13:20 KJV) He that walketh with wise men shall be wise: but a companion of fools shall be destroyed.
“You are what you eat.” “Clothes make the man.” More important is “The nut doesn’t fall far from the tree.” In this case the nut is wisdom. When I am bragging about my children I will sometimes mention that the two biggest factors in their development are heredity and environment. Of course I supplied both.
Left out of the formula is the assumed grace of God. The way that this applies to us is that the Holy Spirit works through people. Sure, my children watched my wife and I. They were watching two people doing everything they could to walk in righteousness and wisdom.
So? Whom do you hang with? Are they leaving a residue of righteousness or a film of filth on your life? We make choices and our friends are on that list. Something to consider next time you get together with the gang.
