The Theme of Murder in Scripture, For Example

Looking again at murder, (or the killing of human life in general) what theme do we see? Well, if you see what I see, God has created humanity in His likeness and called it good. But sin entered into world, followed by death, marring justice and introducing murder into the human race. To His chosen people, God gave His holy and just law on Mount Sinai, condemning murder yet giving war and self-defense as a means of protecting human life.

But for Israel to apply it, they must kill every opposition they find in the promise land with the sword for their holy kingdom to come from this world; and throughout their existence they failed to uphold the law. But God, keeping His word to His prophets, embodied Himself in human flesh. Jesus identified the root cause of murder which is the wishful non-existence of any bearer of God's image with regards to their personality, persuasion, or position. He gave Himself willingly to be gruesomely murdered for the salvation of the world.

Being raised from the dead and sitting at the right hand of the Father, He reconstituted Israel to be a kingdom coming from heaven, a holy kingdom whose promise land expands to all nations; this time with enemies not to be fought with physical weapons but with weapons mighty through God to the pulling down of strongholds. In keeping with the promises of the Messianic Age, courageous Christians throughout the ages by the Holy Spirit have defended the helpless, instituted justice for the second-class citizens, eliminated human sacrifice from continental Europe, saved some lives of the unborn from abortion, etc. One day the Lord will come, raise and judge the whole human race, and consummate the new heavens and new earth where there will be no violence and hatred. 

Now your description is going to look different than mine, but do you get the point?
