When we let a “little” sin into our lives, it is the same as allowing a lot. In 1 Corinthians 5:6 Paul says, Your boasting is not good. Don’t you know that a little yeast works through the whole batch of dough? There is no such things as a little sin. Sin is sin and it works its way into who we are. Let us be mindful of what and who we allow into our lives.
