Psalm 119:11 says, I have hidden your word in my heart that I might not sin against you. I have found that memorising scripture has been very useful in my Christian walk. Luke 6:45 says A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of. If you fill your heart (and mind) with good things like the Word, then that will flow over into your words and actions.
