Why bother having prayer chains, then? Why ask *anyone* to pray for you?
C. S. Lewis covered this one pretty well in Narnia.
"Well, tuck in," said Fledge, taking a big mouthful of grass. Then he raised his head, still chewing and with bits of grass sticking out on each side of his mouth like whiskers, and said, "Come on, you two. Don't be shy. There's plenty for us all."
"But we can't eat grass," said Digory.
"H'm, h'm," said Fledge, speaking with his mouth full. "Well - h'm - don't know quite what you'll do then. Very good grass too."
Polly and Digory stared at one another in dismay.
"Well, I do think someone might have arranged about our meals," said Digory.
"I'm sure Aslan would have, if you'd asked him," said Fledge.
"Wouldn't he know without being asked?" said Polly.
"I've no doubt he would," said the Horse (still with his mouth full). "But I've a sort of idea he likes to be asked."
The funny thing about your quoting of C.S. Lewis is that you’re proving my own point for me.
Why not pray directly to the Father? Why do you need dead people who probably don’t even hear you to pray for you?
Why not just go and ask directly?
Sounds vaguely like mindreading to me.
