The literal translation of this phrase is, all things are stripped and stunned. This is the force of the Greek words. The figure is that of an athlete in the Coliseum who has fought his best in the arena, and has at length fallen at the feet of his adversary, disarmed and broken down in helplessness. There he lies, unable to strike a blow, or lift his arm. He is stripped and stunned, disarmed and disabled, and there is nothing left for him but to lie at the feet of his adversary and throw up his arms for mercy.
Now this is the position that God wants to bring us to, where we shall cease our struggles and our attempts at self-defence or self-improvement, and throw ourselves helplessly upon the mercy of God. This is the sinner's only hope, and when he thus lies at the feet of mercy, Jesus is ready to lift him up and give him that free salvation which is waiting for all.
This, too, is the greatest need of the Christian seeking a deeper and higher life, to come to a full realization of his nothingness and helplessness, and to lie down, stripped and stunned at the feet of Jesus.
