“no future.” The evil person will not have everlasting life.
“lamp of the wicked will be put out.” This is an idiom, meaning the evil person will die. The wicked will die in the Lake of Fire. They will not live forever in torment, as many people teach, but will burn up in the flames and be annihilated.
[For more information on annihilation in the Lake of Fire, see Appendix 5, “Annihilation in the Lake of Fire.”]
