Okay, this is going way better than the conversation I'm having elsewhere!! So glad!
Alright, so to summarize: everybody knows that our Lord commanded us to kill a murderer should he/she be proven guilty, but that was in the Old Testament, right?
Yet in the New Testament, God sends down His precious Son to take the penalty of death we were all due for our sin upon Himself. Christ paid the death penalty we all deserved.
And yet, there are good objections to made on both sides. God is the only one who can truly judge the heart of any human being, only He knows when we are truly guilty, truly lost, and only He can judge us. Objection against the death penalty.
Objection for the death penalty: But not only did the Lord command us to kill murderers, His attitude towards murder has not changed over the centuries since that command, so should we not still carry out His Words?
There's a lot to be said. For myself, this is the way I look at it: the life of a human being, a person made in the image of God, is precious beyond almost anything else. As in, if one were to destroy the image of God(kill someone) they should be punished in an appropriate manner equal to their evil. What kind of punishment is appropriate, however, and suppose such a death was an accident, or was committed under other extenuating circumstances?
There are many scenarios we could discuss, each complicated and diverse, each bearing their own conclusions concerning the morality of the death penalty. Unfortunately, I have to be somewhere soon, so I don't have the time to write out everything I want to. So instead I'll ask this: If the Lord commanded us to kill murderers in the Old Testament, and then sentenced His own Son to bear our sins and their eternal consequences for us, what should we learn from this? And since Jesus preached that we should not retaliate against our neighbor, giving evil for evil but rather good for evil, how does that lesson work with what our Father has already commanded? How can He tell us to kill murderers, and yet also tell us not to take vengeance?
Surely there's a difference.
