The Supremacy of Christ and the sorrow of calamity

I am grateful to my colleague Revd Precious Omuku for passing this John Piper sermon on to me. I would be grateful to anyone with time to listen (it is only on audio, but like all the JPiper sermons I have heard or read, it is well worth listening to) –

I have an outstanding question: As the cry ‘my God, why have you forsaken me?’ rang out, was this God in Christ identifying with those (intellectual) children who do not have the privilege of understanding this?
