What does the bible say is the future for all of mankind?

It's a progressive unfolding of events, all designed to usher in the New Kingdom of God and the revealing of Jesus Christ.

This is listed primarily in the Book of Revelation, and others.

God's future is not for all of mankind, it's for only for those worship him in an acceptable way, like Noah and his family did, all others lost their life.

Jehovah has wonderful things in store for those who love him! Just look at what his Word says about life on the Paradise earth after this corrupt system is did away with. 

Plenty of food to eat: “There will come to be plenty of grain [or, food] on the earth; on the top of the mountains there will be an overflow.” Psalm 72:16. 

Good housing: “They will certainly build houses and have occupancy.” Isaiah 65:21. 

Enjoyable work: “The work of their own hands my chosen ones will use to the full. They will not toil for nothing.” Isaiah 65:22, 23. 

No sickness: “No resident will say: ‘I am sick.’” Isaiah 33:24. 

No disabilities: “At that time the eyes of the blind ones will be opened, and the very ears of the deaf ones will be unstopped. At that time the lame one will climb up just as a stag [a male deer] does, and the tongue of the speechless one will cry out in gladness.” Isaiah 35:5, 6. 

No pain, sorrow, death: “God will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away.” Revelation 21:4. 

No war: “God is making wars to cease to the extremity of the earth.” Psalm 46:9. 

Everlasting life: “The righteous themselves will possess the earth, and they will reside forever upon it.” Psalm 37:29.

"Therefore, just as sin entered the world through one man, and death through sin, so also death was passed on to all men, because all sinned."

"But now He [the Son of Man] has appeared once for all at the end of the ages to do away with sin by the sacrifice of Himself. Just as man is appointed to die once, and after that to face judgment, so also Christ was offered once to bear the sins of many; and He will appear a second time, not to bear sin, but to bring salvation to those who eagerly await Him.…"

Have you read the Book of Revelation? The world will be deceived, and eventually be destroyed. Those that believe in the Lord Jesus Christ will escape the destruction.

FOR THE SAVED WE WILL LIVE FOREVER

THE UNSAVED WILL FAIL JUDGMENT AND GO TO FIRE WHICH is permanent death

There's gonna be a reckoning....

There's gonna be a purge.

God is waiting for the last soul that can be saved, to be saved for it is not His will that any should perish. That last soul will complete His Holy Temple, which is the bride of Christ; the church.

At that time, the faithful will be taken up to heaven.... all the earth will be subjected to unthinkable tortures. People will search for death but it will elude them. Then God's elect will return with Christ; an army.... and with the breath of His mouth He will destroy all evil. The heavens and the earth will be rolled up like a scroll and there will be a new heaven and a new earth.

Pick a side and fight. God is recruiting.

If you are a coward, you are not allowed in His army.

You will be hated.

You will be unpopular.

You may be martyred.

And, man... I'm telling you.... HE'S WORTH IT!

Mankind isn't lumped into one group according to the Bible. There are those who trust in God, and those who don't trust in God. There are those who trusted God and then quit, and those are counted as those who didn't trust in God.

One part of Mankind will go to eternal torment, I think it is because they would otherwise victimize each other for all eternity; their nature being that way as we see in human history. The redeemed who trust God are changed to where that evil nature is no longer present in them.

This is one of my favorite parables in the Bible concerning the saved and those not saved.

Galatians 4

26 But the Jerusalem that is above is free, and she is our mother. 27 For it is written:

“Be glad, barren woman,

you who never bore a child;

shout for joy and cry aloud,

you who were never in labor;

because more are the children of the desolate woman

than of her who has a husband.”

Revelation 21:4

"And he will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away.”

God will restore the earth and people will be resurrected who obeyed Him. So he will bring about his promise of everlasting life and bringing his original purpose.

It says lots of stuff, none of it based in reality and none of it valid.
