Why don't you find it and post the scripture here for all to see?
I am looking at a tree outside my window. How about you pray that it moves a few feet to the right. When that fails, I will get a shovel and dig it up and move it. That should prove two things: 1.) nothing fails like prayer 2.) God helps those who help themselves
3.) Some people will do anything to prove that there is no God. 4.) If God had wanted the tree a few feet to the right, He would have put it there the first time.
