I always understood the passage in 1Ti. 2:4 to mean that god had a strong desire for everyone to be saved, past, present, and future. But the rest of the Bible does not support universalism. Jesus makes it clear that the vast majority will enter into the wrong gate.
I also thought god's will was inviolable. What god wants, god gets. Nothing can stand in the way of his will. No amount of human free will can change that. So if even one person goes unsaved, it has to be because god didn't want that person to be saved. How much more true does that have to be if most people will not be saved?
All of that is before you get to the declaration in Romans 9 that some are created to be vessels of destruction. This means the Bible offers two opposing views of god's will for salvation. One view is that god wants everyone to be saved. And the other view is that there are some created who were never intended to be saved. Which is it?
Yes.
The bible contains many statements which one must "rightly divide" -or put in the correct order.
It is also stated that the word of the Lord is "line upon line", "precept upon precept", here a a little and there a little"
All of the bible supports the same thing -and it must all be taken together to be understood.
God is ABLE to destroy both body and spirit in Gehenna -the lake of fire -but that is not necessarily what WILL happen. It is possible -and there must be an ultimatum -but God turning all to righteousness is also possible.
An individual must eventually choose -but as it is the correct choice and there is no valid reason not to choose it, God may be able to bring all to that choice. There are many verses which suggest such -and actually apparently state as much. The other verses are all true -but some refer to the end result, and others to various points in the process.
This is the most important verse (IMO) concerning that fire.....
1 Corinthians 3:13
Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
1 Corinthians 3:14
If any man's work abide which he hath built thereupon, he shall receive a reward.
1 Corinthians 3:15
If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
Notice that though some will be cast into the lake of fire, death and the grave are eventually cast into the lake of fire.....
Rev 20:14And death and hell were cast into the lake of fire.
Also....
20But now is Christ risen from the dead,
and become the firstfruits of them that slept.
21For since by man
came death, by man
came also the resurrection of the dead.
22For as in Adam all die, even so in Christ shall all be made alive. 23But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
24Then
cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.
25For he must reign, till he hath put all enemies under his feet.
26The last enemy that shall be destroyed is death.
