Now understand this, Jesus is for self-defense but he is against revenge. Romans 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. We as true Christians are not to take revenge; our Lord Jesus will take his revenge out on the wicked. Now if someone threatens you it is not a sin to protect yourself and in fact it is down right biblical. 2 Thessalonians1: 7. And to you who are troubled rest with us, when the Lord Jesus shall be revealed from heaven with his mighty angels, 8. In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: 9. Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power;. You see those who do not follow Jesus he will take violent actions against them. What will I be doing when Jesus takes revenge on those in false religions, drug users, whores, abortion supporters, Marxists and other evil folks? Psalms 58:10. The righteous shall rejoice when he seeth the vengeance: he shall wash his feet in the blood of the wicked.
