“But you and I both ask for help from people other than God.”
Yes, and, surprisingly, my prayers are always answered when my sister in Christ prays with me. We both pray to God directly, and not to Mary or Dick, Tom or Harry.
If you have ever asked someone else for help, you have made a prayer to that person. Just as a lawyer submits a prayer to a judge. Just as anone seeking information might say “pray tell me”. Your problem isn’t theological; it’s semantic. Open a dictionary, for Pete’s sake.
