Rom 13:1 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.
Rom 13:2 Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation.
Rom 13:3 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:
Rom 13:4 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.
God allowed nations and kingdoms to take down nations if they got too cruel towards people and perverting God's truth.
Like Babylon that rode on eagle's wings and prospered because king Nebuchadnezzar acknowledged the God of Israel as the greatest God.
But his son blew it and the kingdom was stripped from them and given to the Medes and Persians.
God used Israel to take down cruel and false religious nations.
And they could be stoned for killing a person.
So capital punishment seems like it would be justified to do.
But this applies to the operation of the heathen as rulers and authority.
Mat 5:43 Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy.
Mat 5:44 But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you.
Mat 5:45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
Rom 12:17 Recompense to no man evil for evil. Provide things honest in the sight of all men.
Rom 12:18 If it be possible, as much as lieth in you, live peaceably with all men.
Rom 12:19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
Rom 12:20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.
Rom 12:21 Be not overcome of evil, but overcome evil with good.
Luk 3:14 And the soldiers likewise demanded of him, saying, And what shall we do? And he said unto them, Do violence to no man, neither accuse any falsely; and be content with your wages.
Approving of capital punishment applies to the heathen the rulers and authority.
But does not apply to the saints for they are to not want any harm to come to a person no matter what they did.
For that is love and love is the fulfilling of the law.
John the Baptist told the soldiers to do no violence to any person which means do not participate in war and do not physically punish anyone and treat them cruelly.
There is plenty of heathen to do the fighting and punishing.
The saints are not to be involved and be different than the world.
Some saints say I must join the military and fight but not only is it wrong but not required to get results.
God determines who falls and stands your participation will not matter.
God does not need your participation and He wants you to stay out of it.
Isa 31:4 For thus hath the LORD spoken unto me, Like as the lion and the young lion roaring on his prey, when a multitude of shepherds is called forth against him, he will not be afraid of their voice, nor abase himself for the noise of them: so shall the LORD of hosts come down to fight for mount Zion, and for the hill thereof.
Isa 31:5 As birds flying, so will the LORD of hosts defend Jerusalem; defending also he will deliver it; and passing over he will preserve it.
Like here the 1967, 6 day war, where Israeli fighter pilots paved the way to win this war.
During the 6 day war in June 1967, Israel faced a combined coalition of neighboring Arab nations—primarily Egypt, Jordan, and Syria, supported by other states like Iraq—that held a significant numerical and technological superiority in troops and heavy equipment.
The mobilizing Arab coalition deployed over 500,000 troops, whereas Israel had roughly 264,000 (largely reliant on rapid civilian reserves).
Arab forces possessed over 2000 tanks, compared to Israel's roughly 800 tanks.
Arab nations had nearly 1000 combat aircraft (including advanced Soviet-supplied MiG-21s), while the Israeli Air Force operated around 300 aircraft.
While facing roughly a 2-to-1 disadvantage in personnel and tanks, and a 3-to-1 disadvantage in aircraft, Israel launched a massive preemptive surprise airstrike on June 5, 1967, destroying the majority of Egyptian and regional air forces on the ground.
This swift capture of air supremacy, combined with superior training, tactical organization, and high operational sortie rates, allowed Israel to decisively defeat the coalition forces and secure victory within six days.
Because God determines who falls and stands.
It did not matter if Israel had the disadvantage God said like birds flying He will take back Jerusalem which Israel took back Jerusalem.
Rom 11:25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
Rom 11:26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
Rom 11:27 For this is my covenant unto them, when I shall take away their sins.
But they could fight physically still operating by the Old Testament not a New Testament saint.
I know some people claiming to be a saint are gung ho to fight for their nation and freedom not liking to be a wimp which I was in the military.
But it would be disobedience so would it be worth it.
And God does not need you to fight and does not want you to fight.
If God wants them to fall they will fall no matter the odds.
Capital punishment should not be endorsed by Christians.
Let the heathen do their job and the Christians do their job.
