In Eph. 4:10, " He that descended is the same also that ascended far above all heavens, that he might fill ALL things!" And human salvation is the most important of those All things. Our future is very important to God, and he is smart enough to know how to save us all. He is loving enough for all of us to make it. He is merciful enough, graceful enough, in all things required for universal salvation, God and Christ are enough.
Yes they are, but they don't force anyone to love them. There
will be people who will not change.
"Yet a little while and the wicked man will be no more; and you will look carefully for his place and he will not be there...The wicked plots against the righteous and gnashes at him with his teeth. The Lord laughs at him, for He sees his day coming." (Psalm 37:10,12,13, NASB)
"Though the wicked is shown favor,
he does not learn righteousness; he deals unjustly in the land of uprightness, and does not perceive the majesty of the LORD." (Isaiah 26:10, NASB)
So even if the wicked were given a chance to live in the paradise earth that is foretold, he will not be good. He will continue to "deal unjustly."
