The truth is, dedication of the life to any thing or anyone short of God Himself, is a prostitution of noble powers and must bring a harvest of grief and disappointment at last. Only God is worthy of the soul He has made in His own image. To devote our lives to any cause, however worthy, is to sell ourselves short. Not money, position, fame, can justly claim our devotion. Art, literature, music also fall short. And, if God is forgotten, even the loftiest and most unselfish task is unworthy of the souls full surrender. Complete dedication unto death in the cause of freedom, for instance, is a touching thing and has given to history many of her greatest heroes, but only the God of freedom should have our last full measure of devotion. These are strenuous times and men are being recruited everywhere to devote themselves to one or another master. Let us be careful. No one has any true right to claim my life except the One who gave His own life for my redemption. If He gets my full dedication then I may engage in any good and worthy cause under His Spirit's guidance. But anything short of complete devotion to Christ is inadequate and must end in futility and loss.
