People of the world are out of control – as is evidence by the most recent London mosque attack.) This "you kill us, we'll kill you back" mentality comes straight from man's carnal, fallen nature!
Romans 10:1. My Brothers, The desire of my heart, and my intercession with Elohim for them is that they might have life. 2. For I bear them witness that there is in them a zeal for Elohim; but it is not according to knowledge. 3. For they do not know the righteousness of Elohim, but seek to establish their own righteousness: and, therefore, they have not submitted themselves to the righteousness of Elohim. (AENT)
2 Timothy 3: 1. But know this: That in the latter days hard times will come: 2. and men will be lovers of themselves and lovers of money, boasters, proud, revilers, unyielding towards their own people, deniers of grace, wicked, 3. unloving, addicted to irreconcilable malicious gossips, ferocious, haters of the good, 4. treacherous, rash, inflated, attached to pleasure more than to the love of Elohim, 5. having a form of respect for Elohim but wide from the power of Elohim. Them who are such, repel from you. 6. For of them are they who creep into this and that house and captivate the women who are plunged in sins and led away by divers lusts, 7. who are always learning, and can never come to the knowledge of the truth. (AENT)
James 4: 1. From where is it, that there are among you arguments and conflicts? Is it not from the lusts which war in your members? 2. You covet but do not possess; and you kill and envy, and effect nothing: and you fight and make attacks; and you do not have, because you do not ask. 3. You ask, and do not receive because you ask wickedly, that you may feed your lusts. 4. You adulterers, don’t you know that the love of the world is hatred towards Elohim? He therefore who chooses to be a lover of this world is the enemy of Elohim. (AENT)
Romans 12: 19. And be you not avengers of yourselves, my beloved: but give place to wrath. For it is written: If you do not execute judgment for yourself, I will execute judgment for you, says Elohim. 20. And if your adversary be hungry, feed him: and if he be thirsty, give him drink. For if you do these things, you will heap coals of fire on his head. 21. Do not be overcome by evil; but overcome evil with good. (AENT)
See also D’varim 32:35; Psalm 94:1; Prov. 20:22 There are no directives from B’resheet/Genesis to Revelation which counsels anyone to take vengeance upon their adversaries. YHWH says, “vengeance belongs to Me”; He will judge and resolve all matters according to His Righteous Judgment. The idea of taking vengeance upon others, as in jihad or holy war against the infidels, is rooted in fear and heathenism by those who put their faith in self rather than in Elohim.
