What does Jesus, the Lord, do when he works a miracle? He replaces the burden of anxious care we feel we must carry, and instead of it, he inserts his mediation for us with the Father. If we are out there in a boat on a stormy lake, thinking we must do something drastic or we might drown, and he comes along and does a miracle, the miracle he tends to do is one where he makes his close relationship of peace with the Father into a substitute for our anxious care. That shows us what he is for us. He is the human who knows what the catastrophe must be like for us, and who has such a relationship with the Father that it can fill the gap between us and the Father, to meet that need and quell our cares and fears. There is one God, and one mediator between mankind and God, the man, Christ Jesus. On the cross, he took the wrath and filled the gap between us and God. Alive, raised by God, he fills the gap for us still. He does so forever.
