I'm more merciful than He will be on Judgment Day to murderers who don't repent of murdering innocent people and Christians. See post #512.
YOu are speaking from emnotion and opinion and not from Scripture! You deny the word of god by your own emotions. Which is normal for all believers if they make their emotions their point of reference instead of the word of God!
Genesis 9:5-6
King James Version
5 And surely your blood of your lives will I require; at the hand of every beast will I require it, and at the hand of man; at the hand of every man's brother will I require the life of man.
6 Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made he man.
Romans 13
King James Version
13 Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God.
2 Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation.
3 For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? do that which is good, and thou shalt have praise of the same:
4 For he is the minister of God to thee for good. 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.
5 Wherefore ye must needs be subject, not only for wrath, but also for conscience sake.
Your job is to biblically, not emotionally, prove that these verses are not valid! Noahs command was for Noah, shem Ham and Japheth and their descendants, which is the whole human race! So even pagans were bound by this law when the Mosaic Law was given. This wasn't nullified!
6 For for this cause pay ye tribute also: for they are God's ministers, attending continually upon this very thing.
Also for the NT prove Paul was condemning the death penalty issued by governmental authorities for real crimes! Remember Paul wrote this under the Inspiration of the Holy Spirit long after Jesus had mercy to the adulteress!
