The End will Come
“Then the end will come, when he hands over the kingdom to God the Father after he has destroyed all dominion, authority, and power” (1 Corinthians 15:26).
Evil entered the universe. And the day will come when evil exits it. Using the terms for evil angels [demons] familiar to first century readers [deominion, authority, power], Paul assures us that God is in control. The future is assured. The resurrected Christ will triumph, putting down Satan and his original followers, ending the rule of death, and bringing “everything” under the control of the Father and his Son.
The key word in this verse is “destroyed.” The Greek here is katargeo, which means to render ineffectual or inoperative, to abolish or nullify. Demons who once ruled this dark world as dominions and authorities and powers will be stripped of their influence. The “powers that be” are destined to become the “powers that were” and “the powers that are no more.”
Stripped of all authority the beings that terrified humankind will be exposed as the frauds they have always been, pretenders to the position which is occupied by God alone.
