1 Samuel 13:14

And we might find many things in the Holy Books which make manifest the simplicity and uprightness of heart of this man of God, and that also which was said by the Lord unto Samuel, "I have found a man according to My heart," testified unto the purity of David's heart, and it is well known that simplicity is born of purity of heart. — 13 Ascetic Discourses, Discourse 4 -- On Faith: First Discourse on Simplicity
