THE RESTRAINING POWER IN THE BIBLE, that now restrains the Antichrist but will be removed.
The power that holds back Satan from bringing the final apostasy and unveiling of his Satan-possessed false Christ (the Antichrist) must be supernatural. It must be God’s power in operation that holds back Satan, so that the “man of sin,” “the son of destruction” (v. 3) won’t be able to come until God permits it by removing the restraining power. The reason for the restraint was so that the Antichrist would be revealed at God’s appointed time and no sooner, just as was Christ (Gal. 4:4), because God controls Satan.
2 Thessalonians 2:6
6 And you know what is restraining him now so that he may be revealed in his time. 7 For the mystery of lawlessness is already at work. Only he who now restrains it will do so until he is out of the way.
