How should we handle our anger towards those Killing Christians?

1 Thessalonians
Chapter 5

1 But of the times and the seasons, brethren, ye have no need that I write unto you.
2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
4 But ye, brethren, are not in darkness, that that day should overtake you as a thief.
5 Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
6 Therefore let us not sleep, as do others; but let us watch and be sober.
7 For they that sleep sleep in the night; and they that be drunken are drunken in the night.
8 But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation.
9 For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ,
10 Who died for us, that, whether we wake or sleep, we should live together with him.
11 Wherefore comfort yourselves together, and edify one another, even as also ye do.
12 And we beseech you, brethren, to know them which labour among you, and are over you in the Lord, and admonish you;
13 And to esteem them very highly in love for their work's sake. And be at peace among yourselves.
14 Now we exhort you, brethren, warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all men.
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.
16 Rejoice evermore.
17 Pray without ceasing.
18 In every thing give thanks: for this is the will of God in Christ Jesus concerning you.
19 Quench not the Spirit.
20 Despise not prophesyings.
21 Prove all things; hold fast that which is good.
22 Abstain from all appearance of evil.
23 And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
24 Faithful is he that calleth you, who also will do it.
25 Brethren, pray for us.
26 Greet all the brethren with an holy kiss.
27 I charge you by the Lord that this epistle be read unto all the holy brethren.
28 The grace of our Lord Jesus Christ be with you. Amen. (The first epistle to the Thessalonians was written from Athens.)

I truly believe this Chapter was written for just such a time as now. We cannot allow our selves to be those that deliver the wrath of God, for we are "children of the light" , we represent what God is like and he is not vengeful , but he is just and will bring his wrath upon the evil ones. It is not our place to determine the how or the when it is God's. Do not think that God will not punish evil , just remember it will be at a time and place of his choosing. And no army can stand up to the might of the lord's angels when they return to Earth to do his work. As strong a military as we have in this country we are but a pebble in bottom of a dried up river compared to his might.
So keep on praying and serving the Master as he is in control and if you are of a group that puts forth terror towards Christians turn to him now and let him forgive you. He is the way and the light and no one gets to heaven except through Christ.

Amen
