"But those enemies of mine who did not want me to be king over them - bring them here and kill them in front of me." - Luke 19:27
"Your enemies… Your foes… You will burn them up as in a blazing furnace. The LORD will swallow them up in His wrath, and His fire will consume them." - Ps. 21:8-9
What is the final end of God's enemies?
Let's start with some general verses concerning God's enemies.
And My hand takes hold on justice,
I will render vengeance on My adversaries,
And I will repay those who hate Me." Deut. 32:41
As wax melts before the fire,
So let the wicked perish before God." Ps. 68:2
For, behold, Your enemies will perish;
All who do iniquity will be scattered." - Ps. 92:9
And all your enemies will be cut off." - Micah 5:9
The LORD is avenging and wrathful.
The LORD takes vengeance on His adversaries,
And He reserves wrath for His enemies." - Nahum 1:2
And like dew which soon disappears,
Like chaff which is blown away from the threshing floor
And like smoke from a chimney." - Hosea 13:3
The Wicked - some specific verses concerning wicked people:
And the enemies of the LORD will be like the glory of the pastures,
They vanish—like smoke they vanish away." Ps. 37:20
The hairy crown of him who goes on in his guilty deeds." - Ps. 68:21
Death, the last enemy
"God raised Him up again, putting an end to the agony of death, since it was impossible for Him to be held in its power." - Acts 2:24
From this study, it became clear that God was going to wipe out all enemies: wicked creatures, death, hades, sin and the like... "for our God is a consuming fire" (Heb. 12:29). His mercy and compassion run deep. But even now as "mercy triumphs over judgment" (James 2:13) there is coming a Day of wrath, "a certain fearful expectation of judgment and a fury of fire which will consume the adversaries" (Heb. 10:27).
