Objection 16 · Prayer doesn't work

Tested under controlled conditions, intercessory prayer fails.

The objection, in full

The 2006 STEP study (Templeton-funded, ten years, 1,800 cardiac patients) found no benefit from intercessory prayer — and a slight negative effect for those who knew they were prayed for. Amputees never regrow limbs. Catholic and Protestant child mortality rates track local medicine, not local devotion. If prayer is real communication with an omnipotent friend, the silence on the line is deafening.

The proper, if somewhat ungainly, formulation is: those who knew they were being prayed for had a slightly higher rate of complications.
— STEP Project, 2006

or, in plain terms —If prayer worked, amputees would grow limbs back. They don't.

My mother prayed for years. She got something better than she asked for.

My mother Monica prayed for years that I would not go to Rome, because she feared I would be lost there. I went to Rome anyway, and there I was found — converted, baptized, returned to the faith she had wanted for me. She had asked for one thing and been given another. The thing she had been given was the thing she had really wanted, but she had not known how to name it.

This is the shape of prayer in a fallen world. We pray with the desires we have, which are mixed and partial. God answers, when he answers, the deeper desire we did not know we had. The prayers that look unanswered are sometimes answered at a depth we could not have specified.

I will not pretend this consoles every grief. The mother whose child dies prayed in a depth I have not touched. But I will say what I have seen: that those who pray long and honestly are rarely surprised, in the end, that God did not give them what they asked. They are surprised by what he gave instead.
