“The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, NOT WANTING ANYONE TO PERISH, but everyone to come to repentance.”
—2 Peter 3:9.

Jesus wants all to be saved and escape the destruction awaiting the sin-polluted earth.

“The day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and THE EARTH AND EVERYTHING IN IT WILL BE BURNED UP [margin]. . . . But in keeping with his promise we are looking forward to a new heaven and a new earth, the home of righteousness.”
—2 Peter 3:10, 13.

As long as sin rules in this world, it will continue to multiply human misery. So sin has to be completely destroyed. If people refuse to let go of their sins, they will be consumed with them in “the lake of fire” (Revelation 20:14-15). Christ’s final heartbreak comes when He must finally cleanse the universe of evil, put an end to sin, and destroy those who hold on to their sin, those for whom He died and longed to save.
