The false doctrine that some men were created to never have a savior is one of the most damnable heresies to ever be spread across the earth.
Well, first of all, God did not
create any man to not have a Savior.
He created one man, a direct creation, gave him a helpmeet, fellowshipped with him face to face, gave him everything he needed, put him in a garden and gave him charge of it, and this guy blew it by believing and obeying a fellow creature instead of the creator.
You can find his story in Genesis 1 to 3.
Paul further writes of the effect of this guy's blowing it in Romans 5:12.
Now, from this fellow came all men, and God elected many of his race unto salvation in Christ Jesus, bypassing some according to His sovereign good pleasure, and providing a Savior for those whom He elected unto salvation.
Those He bypassed and left to their own sin, of course, do not have a Savior.
In the Book of Revelation a book is described as having been written before the foundation of the world, a term which I take and understand to be a time when Adam and Eve was not yet, the Garden of Eden was not yet, the stars and the heavens and everything in it were not yet, and therefore there was no man in existence who had the "choice" to reject God or accept Him, and who rejected God, and accepted Him.
In Revelation 13:8, it is written that those whose names were written in this book were not deceived by the anti-Christ, neither did they bow down to him, while there are those who did worship the anti-Christ, and were deceived by him, and significantly, we again find the phrase "whose names were not written in the Lamb's Book of Life ......", by which we can reasonably deduct that the reason they bowed down to the anti-Christ and were deceived by him is because their names were not written in the Lamb's Book of Life.
In the 20th chapter of the same book of Revelation a judgment in the heavens is being meted out, and on a Great White Throne sat Him before whose face the heavens fled away, and Satan and his angels were judged, and then, books were opened by which the dead were judged, and among other things they were cast into the lake of fire along with Satan and his angels because their names were not found in the Lamb's Book of Life.
Please notice several significant phrases: "before the foundation of the world" and "Lamb's Book of Life", denoting the time when the book came into existence, and the ownership and authorship of the book. We all know who the Lamb is, and I trust you do. If He wrote this book, and the names in it, then it follows that those whose names He did not write, he did not write because He did not want to, not because He was not aware of them.
Is the Lamb the Savior ? If He is, then those whose names He wrote have a Savior, and those whose names He did not write do not have a Savior. Simple as 1, 2, 3.
