...that I may be His own and live under Him in His kingdom and serve Him in everlasting righteousness, innocence, and blessedness, just as He is risen from the dead, lives and reigns to all eternity. This is most certainly true. (The Small Catechism: Second Article, Part 3)
In the Name + of Jesus. Amen. WHY did Jesus do what He did? What's the end result? The Catechism lays it out: that we would be His own and live under Jesus in His kingdom. Another way of saying this is that we are rescued from trying to rule the world ourselves. That's our main problem. We want the world to be OUR kingdom, and WE want to be the kings or queens or dictators, with others doing our bidding. Not only do we not want others in charge, we don't want God Himself to be God!
So, Jesus saves us from that by His suffering and death and holy, precious blood--by His death and resurrection. He rescues us to bring us out of a kingdom that is ruled by self-centered sinners and into a kingdom ruled by Him in grace and mercy and forgiveness.
Jesus rescues you from a life where "you get what you deserve" to make you a part of a family in which you get what you don't deserve and don't get what you do have coming.
Jesus rescues you from wickedness, guilt, and a curse in order to make you righteous, innocent, and blessed.
Jesus rescues you from the curse of death, by giving you everlasting life.
Jesus rescues you from the kingdom of the devil--a kingdom of slavery to sin--and brings you into His kingdom of everlasting goodness and rest.
Jesus did all that He did for you:.to save you; to make you the Lord's; and to rescue you from sin and death and devil and hell and even yourself. He brings you, by His Cross and empty tomb, through water, Word, Body and Blood, from a kingdom of death and misery to one of everlasting righteousness, innocence, and blessedness. This is most certainly true. In the Name + of Jesus. Amen.
Have no fear, little flock; Have no fear, little flock, For the Father has chosen to give you the Kingdom; Have no fear, little flock! (Have No Fear, Little Flock, LSB 735:1)
