PRAYER governs conduct and conduct makes character. Conduct, is what we do; character, is what we are. Conduct is the outward life. Character is the life unseen, hidden within, yet evidenced by that which is seen. Conduct is external, seen from without; character is internal — operating within. In the economy of grace conduct is the offspring of character. Character is the state of the heart, conduct its outward expression. Character is the root of the tree, conduct, the fruit it bears.
