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
We are living in perilous days by which we might enter into the most exciting days this world has ever seen in the coming months and years. The Bible and its 100% prophecy fulfillment record predicts there will come a time when a man of lawlessness or sin will be revealed and this person will deceive the world for a period of 42 months. This person will be known as the Antichrist. The spirit of the Antichrist though is described in 1 John 4:
Every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world."
We see this spirit at work as the anti-God, anti-Christian, anti-morality spirit is making its inroads in every aspect of American culture with record speed. This spirit though--despite its advances--is being held back by the restraining power mentioned in 2 Thessalonians. Scholars agree that this restraining power has to do with the church and the body of believer in Christ all over the world. When this is removed, we see the aftereffects as mentioned later in the same chapter:
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...and for this reason God will send them a strong delusion, that they should believe a lie
When will this restraining power be removed? Only God knows. Until it happens this world will continue to grow more and more wicked as that day approaches.
