" But why would he do this? One possibility is to allow us to bring things to his awareness through prayer that he already knows but wasn’t focusing on. In such cases, God could bring these things to his awareness at will without relying on us. After all, he knows everything. But he does not have to be aware of all he knows, and this withholding of awareness allows us to genuinely inform God of things, not in the sense that he didn’t already know them, but in the sense that he has condescended in such a way as to allow us to recall these things to his awareness. And such an act of recalling would bring with it a genuine, and not feigned, sense of fresh excitement and concern for the prayer being made. "
