No, but her prayer is so effacious that she is able to obtain all these things from her Son, Jesus Christ.
So, her Son pays more attention to her prayers than He does those of others? I thought that He was not a respector of persons. Either He is or He isn't. There is no room for a "he isn't...but..." reply. Jesus is either what He says He is or not. He is either sovereign or not.
She has no prayer to give on our behalf.
She is dead and cannot be asked.
