And in Jesus Christ, His only Son, our Lord who was conceived by the Holy Ghost, born of the Virgin Mary; suffered under Pontius Pilate, was crucified, dead, and buried. He descended into hell. The third day He rose again from the dead. He ascended into heaven, and sits on the right hand of God the Father Almighty. From thence He shall come to judge the living and the dead.
For when we had been created by God the Father, and had received from Him all manner of good, the devil came and led us into disobedience, sin, death, and all evil, so that we fell under His wrath and displeasure and were doomed to eternal damnation, as we had merited and deserved. There was no counsel, help, or comfort until this only and eternal Son of God in His unfathomable goodness had compassion upon our misery and wretchedness, and came from heaven to help us. Those tyrants and jailers, then, are all expelled now, and in their place has come Jesus Christ, Lord of life, righteousness, every blessing, and salvation, and has delivered us poor lost men from the jaws of hell, has won us, made us free, and brought us again into the favor and grace of the Father, and has taken us as His own property under His shelter and protection, that He may govern us by His righteousness, wisdom, power, life, and blessedness.
Let this, then, be the sum of this article that the little word Lord signifies simply as much as Redeemer, i.e., He who has brought us from Satan to God, from death to life, from sin to righteousness, and who preserves us in the same. But all the points which follow in order in this article serve no other end than to explain and express this redemption, how and whereby it was accomplished, that is, how much it cost Him, and what He spent and risked that He might win us and bring us under His dominion, namely, that He became man, conceived and born without sin, of the Holy Ghost and of the Virgin Mary, that He might overcome sin; moreover, that He suffered, died and was buried, that He might make satisfaction for me and pay what I owe, not with silver nor gold, but with His own precious blood. And all this, in order to become my Lord; for He did none of these for Himself, nor had He any need of it. And after that He rose again from the dead, swallowed up and devoured death, and finally ascended into heaven and assumed the government at the Father's right hand, so that the devil and all powers must be subject to Him and lie at His feet, until finally, at the last day, He will completely part and separate us from the wicked world, the devil, death, sin, etc.
