Faith turns the promise into a prophecy. While it is merely a promise it is contingent upon our cooperation; it may or may not be. But when faith claims it, it becomes a prophecy and we go forth feeling that it is something that must be done because God cannot lie.
Faith is the answer from the throne saying, "It is done." Faith is the echo of God's voice. Let us catch it from on high. Let us repeat it and go out to triumph in its glorious power.
Hear the answer from the throne. Claim the promise, doubting one, God has spoken, "It is done." Faith has answered, "It is done;" Hallelujah! It is done.
God is not human, that he should lie, not a human being, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill?
