“Whoever walks with the wise becomes wise, but the companion of fools will suffer harm” (Prov.13:20). “Do not be deceived: ‘Bad company ruins good morals’” (1Cor.15:33).


“Nothing perhaps affects man’s character more than the company he keeps. We catch the ways and tone of those we live and talk with, and unhappily get harm far more easily than good. Disease is infectious, but health is not. Now, if a professing Christian deliberately chooses to be intimate with those who are not friends of God and who cling to the world, his soul is sure to take harm. It is hard enough to serve Christ under any circumstances in such a world as this. But it is doubly hard to do it if we are friends of the thoughtless and ungodly. Mistakes in friendships are the whole reason why some have entirely ceased to grow.” -JC Ryle, The Duties of Parents (emphases mine)
