I will let carnal men carry out the vengeance towards others for that is what carnal man has always done because they have no understanding that if you are willing to kill the killers for your own reasons, you are the same as they are. Followers of Christ recognize sinful ways and stay far from doing them. But Jesus who is our example came as a Lamb... and it is only after the grace period is over and time for this earth age is up that he returns as a lion to destroy(using willing men's hands) all who refused the love of the truth, in exchange for the lie. We can only allow God to work in us personally, we can not speak for another man's heart... but we must try to reach them with the love of the truth. Thy Word oh LORD is truth!
Matt 5:38-39
38 Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth:
39 But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.
KJV
1 Thess 5:15
15 See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men.
KJV
1 Peter 3:9-11
9 Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing.
10 For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile:
11 Let him eschew evil, and do good; let him seek peace, and ensue it.
KJV
Rom 12:18-21
18 If it be possible, as much as lieth in you, live peaceably with all men.
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.
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.
21 Be not overcome of evil, but overcome evil with good.
KJV
John 8:5-11
5 Now Moses in the law commanded us, that such should be stoned: but what sayest thou?
6 This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not.
7 So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
8 And again he stooped down, and wrote on the ground.
9 And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst.
10 When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee?
11 She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.
KJV
Matt 18:25-19:1
25 But forasmuch as he had not to pay, his lord commanded him to be sold, and his wife, and children, and all that he had, and payment to be made.
26 The servant therefore fell down, and worshipped him, saying, Lord, have patience with me, and I will pay thee all.
27 Then the lord of that servant was moved with compassion, and loosed him, and forgave him the debt.
28 But the same servant went out, and found one of his fellowservants, which owed him an hundred pence: and he laid hands on him, and took him by the throat, saying, Pay me that thou owest.
29 And his fellowservant fell down at his feet, and besought him, saying, Have patience with me, and I will pay thee all.
30 And he would not: but went and cast him into prison, till he should pay the debt.
31 So when his fellowservants saw what was done, they were very sorry, and came and told unto their lord all that was done.
32 Then his lord, after that he had called him, said unto him, O thou wicked servant, I forgave thee all that debt, because thou desiredst me:
33 Shouldest not thou also have had compassion on thy fellowservant, even as I had pity on thee?
34 And his lord was wroth, and delivered him to the tormentors, till he should pay all that was due unto him.
35 So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses.
KJV
When there is no man who is willing to kill or return evil for evil for any reason, then is when all evil will have been destroyed.
Adam was not willing to be a killer, nor Eve willing to take vengeance upon Cain, not even God killed Cain for the evil he did to his own brother Abel. God just put Cain outside His presence of protection and care and let Cain wander the earth all alone. But God also made it clear that who ever kills Cain, shall suffer sevenfold. God can put us in positions and situations in life by turning up the heat being in constant torment, and He does use willing hearts to carry out His vengeance or even what we call natural disasters and plagues even all of His creation. But a man of God should not be the punishers. Our concern should be to raise up the dead in the Word so they can live and not die.
Gen 4:15
15 And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.
KJV
Remember that murder is not the unpardonable sin... calling the work of the Spirit, the work of the devils unclean spirit is! So to say a killer must be killed as in an eye for an eye... is not of our new covenant in Christ.
Mark 3:28-30
28 Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme:
29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation:
30 Because they said, He hath an unclean spirit.
KJV
