"It is here that we come to know of what we are accused and guilty, what our trespass is and means. It consists in an alienation from God, a rebellion against him, which ought to be punished in a way that involves our total destruction, and which apart from our annihilation can be punished only by God himself taking our place, and in his Son taking to himself and bearing and suffering the punishment. This is what it costs God to be righteous without annihilating us. The opposition to him in which we find ourselves is so great that it can be overcome and rendered harmless to ourselves only by God, and indeed only by his entering himself into this opposition and bearing the pain of it."
