“By the fact that Christ is Priest He turns God into our Father, and Himself into our Lord. If I regard Him as Priest, then I know that He does nothing but sit in heaven above as our Mercy Seat and there intercedes for us before the Father without ceasing, pleads on our behalf, and says the best for us.
This is the greatest comfort that can come to a human being, and no sweeter sermon can be preached to the human heart. This He has proved in the Gospel by everything He says and does. For He does nothing but serve and help people and offer Himself to everybody.
In addition, in order to atone for us, He burdens Himself at the cost of His life and blood with all the wrath which we have deserved. Is it possible to preach anything more comforting than this to troubled consciences?”
