And David put his hand in his bag, and took there a stone, and slung it, and struck the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.
All Commentaries on 1 Samuel 17:49 Go To 1 Samuel 17
Therefore, let us take in our hands that stone, I mean the cornerstone, the spiritual rock. If Paul could think in these terms of the rock in the desert, no one will in any way feel resentment against me if I understand David’s stone in the same sense.

So, too, in David’s case, it was not the visible stone but the spiritual stone which sank into the barbarian’s head. This is why, at that time, I promised that I would say nothing based on rational arguments. “Our weapons are not merely carnal but spiritual, demolishing sophistries and reasoning and every proud height that raises itself against the knowledge of God.”
