Anything that God speaks, it's absolutely got to produce it, just can't keep from it.
Look at Jesus when He come off the mountain. He was hungry, and He looked on the bush for something to eat, and there was nothing there. He said, "No man eat from you from here henceforth," and just went on. Never screamed over it, He just said, "No man eat from you." One of the apostles heard it. And when they passed by the next day, that tree was withered. See? He spoke His Word and not one bit of doubt but what it was going to be that way, and the life went out of the tree. It has to. God said so.

That's what I was speaking on last night in Abraham. When the Word is spoken by God, just lay hold on it, and it'll create just exactly what it says it'll do. But you can't do it in doubting, and jumping, and up-and-down. You just got to hold on to it. Stay with it. God will make it manifest.
