This has not changedRemember He redeems from all iniquity and purifies unto good works, unbelief is nothing but iniquity Titus 2:14
14 Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.
also remember if we believe not its because we were not of His Sheep for whom He gave Himself for as He makes clear here Jn 10:26
26 But ye believe not, because ye are not of my sheep, as I said unto you. So if He didn't die for one and redeem them, what alternative do they have but to die in their unbelief and sins ?Duh
Unbelievers are not redeemed and die in their sins as per your own quoted words
24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.
