Be sure your sin will find you out.
Numbers 32:22b

My kids hear this verse fairly often. I tell them that it is one of my regular prayers for them because I love them and I don't want them ever to get away with sin. These are comforting and encouraging words! They remind me of Hebrews 12. "For whom the LORD loves He chastens... [chastening] yields the peaceable fruit of righteousness to those who have been trained by it."

It is the mercy of God that He does not leave us in our sin, but that He humbles us, chastens us, and brings us to repentance.
