The reason why there is no record of Jesus ever intervening in the government execution of a murderer is because the Mosaic Law very strongly supported the death penalty in the case of murder and Jesus never once disobeyed the law or taught against it.
Likewise, Paul recognized the justice of the death penalty. When he was brought before the judgment seat of Festus, he said, “For if I be an offender, or have committed any thing worthy of death, I refuse not to die” (Acts 25:11). By this, Paul admitted that there were offenses worthy of death and that the government had the right to administer death in those cases.
He further states in Romans that “But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil” (Romans 13:4).
The Bible doesn't condone the present situation where murderers are housed for life in expensive institutions that innocent citizens are forcibly taxed to pay for who then cause many more murders and create an institutionalized prison gang run environment that prevents most real reform from occurring.
How you guys ever got the idea that it does is beyond me.
Scripture teaches that a murderer can both repent and be saved by God but also executed by the state for the crime of murder. There is no dichotomy.
So if they had dragged a gang member out of town for execution Jesus would have said "let 'im have it"?
