Your response is easily the stupidest thing I’ve ever read. Killing in self-defense is not a sin.
I don’t seem to recall ever writing it is permissable to kill “for the glory of God,” only you said that.
Obviously, you don’t know history, nor the threat Christendom faced at the hands of the Mohammedans. How sad, but predictable of the knee-jerk types such as yourself.

But to answer your Grade School level silly question:
Happy reading!

Gen. 15:14-21 – God blesses Abram through the priest-king Melchizedek after Abram’s war victory over Chedorlaomer and his cohorts. Melchizedek offers a bread and wine sacrifice in thanksgiving for Abram’s victory and Abram gives Melchizedek a tenth of the spoils.

Ex. 15:3 – “The Lord is a man of war, the Lord is his name.”

Deut. 1:41; 20:1,12,19-20; 21:10; Jos. 6:3; Joel 3:9 – some examples where the Lord commands war when the reasons are justified.

Prov. 20:18 – “Plans are established by counsel; by wise guidance wage war.”

Bar. 3:26 – more Old Testament examples where God approves of war.

Matt. 8:5-13 – Jesus praises a Roman centurion warrior for his faith and
cures the centurion’s servant. Jesus would not have responded to the prayer of an evil man unless it was a prayer of repentance. Obviously, although the centurion was a soldier, Jesus did not consider him an evil man, but a very faithful man, even more faithful than anyone else in Israel.

Luke 14:31 – Jesus acknowledges the legitimacy of war in this parable.

Luke 19:27 – Jesus says “But as for these enemies of mine, who did not want me to reign over them, bring them here and slay them before me.” Jesus teaches that not all killing is intrinsically evil.

Luke 22:36 – Jesus says “let him who has no sword sell his mantle and buy one.” Jesus encourages the legitimate defense against an aggressor.

Acts 10:2 – God responds favorably to another centurion’s prayer (Cornelius of the Italian Cohort), even though he was a soldier. The soldier’s “prayers and alms ascended as a memorial before God.”

Heb. 11:32-34 – Paul praises Gideon, Barak, Samson, Jephtha, David and Samuel who conquered kingdoms, enforced justice, became mighty in war and put foreign armies to flight. These men engaged in the legitimate defense of the people of God and were praised for their faithfulness.

Rom. 13:3-4 – Paul commends us to those in authority, and exalts a man who “does not bear the sword in vain.” Paul calls such a man “the servant of God to execute his wrath on the wrongdoer.”

2 Cor. 10:3-4;
1 Tim. 1:18;
Heb. 11:34;
James 4:1;
1 Peter 2:11;
Apoc. 2:16; 11:7; 12:7; 17:14; 19:11,19 – these New Testament passages reveal that the real war to be won is the spiritual war against the flesh and the devil.

Eccl. 3:3– the inspired writer says that there is “a time to kill.” We look
to the Church, the pinnacle and foundation of the truth (1 Tim. 3:15) to
understand when such a time exists. As we have seen, in the context of military action, this time exists only when it is: necessary to repel an aggressor; all other means of repelling the aggressor have been ineffective; there is serious prospects of success; the damage inflicted by the aggressor is lasting, grave and certain; and, the evils and disorders produced by the war must not be graver than the evil eliminated, that is, the act of defense must be proportionate to
the aggressor’s offense.
