Untried character is not reliable. We are to be tried by temptation in order that we may learn to seek wisdom from God and to flee to the stronghold in time of trouble. He alone will be successful in resisting temptation who finds help and grace from God. Individually we stand as did our first parents–face to face with manifold temptations that solicit mind and heart. All heaven is watching with intense interest to see whether we will look unto Jesus and submit ourselves to His will, or whether in the temptation we shall follow the inclinations of the natural heart and the solicitations of the evil one.
