This is the post #25 of the Calvin's Institutes summary series.
As the New Testament clearly teaches, there is no hope of redemption outside Christ, who is the Mediator. In the Old Testament too, it had been declared that God was to be sought through a mediator, pointing to the Mediator who was to come. Through Him and through Him only, do we come to see that "God is our Father to watch over us, govern and nourish us, until he gathers us unto the eternal inheritance of his Kingdom. (Calvin, Institutes, II. vi. section 4.)."
