“Yield yourselves”: every man must be a creature. He can be nothing else but a creature in this life or in the life to come. Even in hell, men will still be creatures, because that is what we are. Only one is self-sufficient in himself, and he is God. But now as Christians we are introduced to the great reality: our calling is to be creatures in this high, tremendous, and glorious way, not because we must be, but by choice.
I am a creature, it is true, but I have a calling to be the creature glorified, I must be the creature, but I do not have to be the creature like the clod in the field, the cabbage that is rotting in the field as the snows melt. I am called to be a creature by choice, on the basis of Christ’s finished work, by faith: the creature glorified. Now I am ready for the war. Now there can be spirituality of a biblical sort. Now there can be a Christian life. Rejected, slain, raised: now we are ready to be used.
