Insufficient, "All sufficient." These two words form the complement of each other and together give the key to an efficient Christian life. The discovery and full conviction of our utter helplessness is the constant condition of spiritual supply. The aim of the Old Testament, therefore, is ever to show man's failure; that of the New, to reveal Christ's sufficiency. He has all things for us, but we cannot receive them till we know that we have nothing.
The very essence, therefore, of Christian perfection is the constant renunciation of our own perfection, and the continual acceptance of Christ's righteousness. And as we receive deeper views of our nothingness and evil, it is but a call to claim more of His rich grace. But it is possible fully to know our insufficiency and yet not take firmly hold of His "all things." This, too, must be done with a faith that will not accept less than ALL. The prophet was angry because the king of Israel had only smitten thrice upon the ground. He should have done it five or six times. He might have had all. So let us meet His greatness and grace.
