Would you consider Eustace and Jill's call to Aslan at the beginning of The Silver Chair a prayer? If so, the personal response that Aslan gave verbally later on was that they could not have been calling him unless he had called to them first.

Probably the most obvious instance that comes to mind is Lucy's call to Aslan when the Dawn Treader is sailing in the dark cloud. Lucy feels better immediately, and soon after, the albatross comes to lead the ship out of the cloud. The albatross also gives that lovely private word to Lucy: "Courage, dear heart."

This is a trickier question than it appears to be at first because there's very little of what we Earthlings would call religious observance in the books. If you wanted to talk to Aslan, well, he was often right there. So I guess one might say that every conversation with Aslan is a kind of prayer.

I like your examples, Mini. From your Eustace/Jill who's-calling-whom example it is a well timed reminder to me that prayer is a personal response to God's reaching out to me, not just some sort of spiritual discipline on a checklist of religious acts. It is easy for me to get Martha-syndrome (Luke 10:38-42) and get so focused on things to do that I miss what is really important, like sitting at Jesus' feet. I pray, but at times I can view it as an interruption to Real Life instead of being the source of my life. Thanks be to God for His mercy on me and patience with me...

I would consider this a prayer when I saw this in Prince Caspian, when he blew the horn of Susan. He was asking for help since he was in the middle of danger and his uncle Miraz tried to suppress the kingdom and make it for himself. He wanted to kill Caspian, so he escaped with the help of his professor. But when he fell into the woods and saw the creatures of Narnia, he felt helpless and really wanted to escape the horror. So when he grabbed the horn, he prayed for the 4 siblings to arrive and help him win the battle against his greedy uncle.. 🙂

Interesting thought, Amarlz. Sometimes prayers don't involve words. When we find ourselves at our wit’s end, we might cry out for help without using words - a call for deliverance because we feel so helpless. The horn could be compared to that. In the book, Caspian doesn't blow the horn while he's running away, but according to the planned time, but it too is a kind of prayer to Aslan to come himself or send the children to aid them in their need. The war is going badly and they've run out of options. Now they are calling out for a miracle.

Tirian's prayer in LB is the one I noticed.
"Aslan! Aslan! Aslan! Come and help us now. Let me be killed. I ask nothing for myself. But come and save all Narnia. Oh, Aslan, Aslan. If you will not come yourself, at least send me the helpers from beyond the world. Or let me call them. Let my voice carry beyond the world."
This is one of the times someone speaks to Aslan without His being there in front of them. (As Miniver pointed out, that doesn't happen very often.) Tirian has never even seen Aslan, yet he trusts Him to hear when he calls, and to have the power to fulfill his request. The last part of his prayer also reminds me a little of the faith of the centurion in Matthew 8 ("Just say the word and...") and of Peter's walking on the water ("If it's really you, tell me to...").

Ooh... I hadn't thought of all that! Great points, hobbit!
