Now, my friends, if you want to be eternally blessed by the battle of your Savior, your heavenly General, nothing more is demanded of you and all men than that you play the part of a believing spectator. The important thing is not that you learn how to fight against sin and Satan from Christ’s example, but the first, the most important, the main thing is that you learn to believe that Christ battled for you, in your place, for your freedom and salvation. Whoever knows and feels his sins, whoever knows that hitherto he has served the devil, that he was full of unbelief, contempt of Gods’ Word, pride, vanity, lust, and love of the world, or that he at least has not really battled against the world, flesh, and Satan, let him merely look to his Savior. This Champion from the stem of David has held the field for us. This Lion from the tribe of Judah has conquered for us. Though you may have fallen ever so deeply, though you may have even begged the devil’s pardon, free yourself from this disgraceful tyranny. Side with Christ; then you are victor over sin and hell. Then Christ also divides the spoils of war with you – forgiveness of sins, righteousness, life, and salvation.
