The Power of Antichrist

Antichrist’s great power will not be his own but will be in accord with the activity of Satan. Energeia (activity), the root of the English word “energy,” describes power in action. It usually refers to God’s power (e. g., Eph. 1:19; 3:7; Phil. 3:21; Col. 1:29; 2:12), but here it describes Satan’s power. Antichrist’s power and signs and false wonders will not only be deceptive tricks, like falsifying his own death and resurrection (Rev. 13:3, 12, 14; 17:8, 11), but also actual manifestations of Satan’s supernatural power. Power (miracles; cf. Matt. 7:22; 11:20, 21, 23, etc.) refers to supernatural acts; signs point to the one who performs them; wonders describes the astonishing results. . . .
