The significance of the testimony of Christ here is great.  God is the author of the Old Testament, no less than of the New Testament; and there is no way by which a true believer in Christ can avoid full acceptance of God's word as revealed in the Old Testament.  It is true now, as it was then, that if men will not believe Moses, they will not believe Christ either.
