God Tries Men to Find Out What Is in Their Hearts

The Lord, your God, proveth you, to know whether ye love the Lord your God, with all your heart and with all your soul. (Deut. 13: 3.)

The Lord thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thy heart. (Deut. 8: 2.)

For now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son, from me. (Gen. 22: 12.)
