This statement indicates that the belief declared by the Prophet was considered by him to be the absolute Truth. His stand was not on the ground of national tradition or group prejudice but on that of sound reasoning. He was the preacher of that Faith: all facts corroborated its truth. It can be imagined from this that what is vital to the caller to the truth is consciousness of reality and not the blind following of national tradition. The vast creative system of God, which is spread out in the shape of heaven and earth, indicates that its Lord is the one and only God. The extensiveness of the system of the universe rules out the possibility of there being more than one God.
