John Stott, a Christian writer and speaker of world renown, wrote about his conviction that Christ's pain was absolutely necessary if we are to have a Savior.
I could never myself believe in God if it were not for the cross. In the real world of pain, how could one worship a God who was immune to it? I turn to that lonely, twisted, tortured figure on the cross, nails through hands and feet, back lacerated, limbs wrenched, brow bleeding from thorn-pricks, mouth dry and intolerably thirsty, plunged in God-forsaken darkness.
That is the God for me. He set aside his immunity to pain. He entered our world of flesh and blood, tears and death.
In Isaiah 53 :1-5, the prophet speaks of Jesus' suffering for us,
Who has believed our message and to whom has the arm of the Lord been revealed? He grew up before him like a tender shoot, and like a root out of dry ground. He had no beauty or majesty to attract us to him, nothing in his appearance that we should desire him. He was despised and rejected by mankind, a man of suffering, and familiar with pain. Like one from whom people hide their faces he was despised, and we held him in low esteem. Surely he took up our pain and bore our suffering, yet we considered him punished by God, stricken by him, and afflicted. But he was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed.
Yes, by his wounds we are healed. Completely. Eternally.
