If you genuinely want to understand the children of God you encounter in this life, pay attention to their words. Their conversations will either condemn them or justify them. For Christ said that what enters your mouth does not defile you, but what comes out of your mouth does. The hidden things of God refer to matters pertaining to the Lord, while the wicked heart speaks the evil within it. If you know what lies within your heart, you will know yourself and be known by God. However, if your heart is wicked, you have not known yourself nor the living Father. For the words you speak shows who rules over you whether it be the Lord or the wicked one. For whatever is in your heart will govern your words and the way you live.
