Antichristâs 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 âenergy,â describes power in action. It usually refers to Godâs power (e. g., Eph. 1:19; 3:7; Phil. 3:21; Col. 1:29; 2:12), but here it describes Satanâs power. Antichristâs 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 Satanâs 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. . . .
