Which is manifest evidence of the righteous judgment of God, that you may be counted worthy of the kingdom of God, for which you also suffer. Since it es a righteous thing with God to repay with tribulation those who trouble you, and to give you who are troubled rest with us when the Lord Jesus is revealed from heaven with His mighty angels.
Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you.
not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come.
Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition. who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.
¿Do you not remember that when I was still with you I told you these things? and now you know what is restraining, that he may be revealed in this own time. For the mystery of lawlessness is already at work; only He who now restrains will do so until He is taken out of the way.
And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved.
And for this reason God will send then strong delusion, that they should believe the lie, that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.
2 Thessalonians 2: 1- 12
Beloved, do not believe every spirit, but test the spirits, whether they are of God; become many false prophets have gone out into the world.
We are of God. He who knows God hears us; he who is not of God does not hear us. by this we know the spirit of truth (form God), and the spirit of error (lie from Satan).
and in this the children of God and children of the evil are manifest: whoever does not practice righteousness is not of God.
By this we know that we love the children of God, when we love God and keep His commandments. For this is the love of God, that we keep His Commandments. And His Commandments are not burdensome.
The test of knowing God is:
Now by this we know that we know Him, if we keep His commandments. He who says, "I know Him" and does not keep His commandments, is a liar, and the truth is not in him. But whoever keeps His word, truly the love of God is perfected in him, by this we know that we are in Him. He who says he abides in Him ought him self also to walk just as He walked.
My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an advocate with the Father, Jesus Christ the righteous.
Whoever transgress and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the father and the Son. If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him.
Peace to the brethren, and love with faith, from God the father and the Lord Jesus Christ. Grace be with all those who love our Lord Jesus Christ in sincerity. Amen
