God uses the foolish things of the world to shame the wise. The thrust of a spear plunging upward piercing the side of God, perforating his bowls, puncturing his heart, collapsing his lungs: this becomes the message of God. The nastiest bit is the Gospel, the good news, your salvation. It’s the foolishness that God could die that our sins could be forgiven by another man’s blood, that salvation is found in the death of a criminal. No glory, just a cross, bowels, blood and bone, the suffocating stench of death, and your salvation where God becomes the propitiation of man.
