The Sermons of Martin Luther

Now here we have the substance of the Gospel. The kingdom of Christ is a kingdom of mercy and grace, in which there is nothing but a continual carrying of the lost. Christ carries our infirmities and sicknesses, he takes our sins upon himself and has patience when we fail. We still always lay about his neck, and yet he does not become weary of carrying us, which should be the greatest comfort for us when we are in conflict with sin.
