Because they CHOSE darkness over light, took the wide road, scoffed!
I believe it is important to note that it is in mans very nature to go against God. I do not see it as humans choosing that road - but only doing what is
natural for us as fallen beings. Mankind does not know anything else but rebellion. Our desires apart from Christ are not pure and even as Believers we must be on guard to submit every thought to the obedience of Christ.
There are many, many people in the world who have heard about Jesus but simply do not care. What causes you to be convicted over your sins and not others? I believe the real issue here is not predestination because whether you're a Calvinist or not each person must wrestle with the fact that it is in the Bible. Whether you believe election or God's foreknowledge - you have it. The unbeliever would ask you, "If God had full knowledge of everything then why did He create knowing many would go to hell and the world would be filled with evil?" Do you believe in God's foreknowledge? If so, was it right for Him to create knowing that more would be lost than saved? Was it wrong to create anyways knowing that the world would be filled with so much violence?
Even thought I lean Calvinist I know there are things I cannot answer because my understanding is so limited. One thing I've come to realize is that predestination is not the issue - not even close. For me, it is why create a world
knowing completely in advance that countless billions would suffer eternal torment if it could have been avoided? We weren't missing out on anything while we were unborn, but the one born that stays lost is sadly created in vain it seems; only to know pain and sorrow that we can't imagine.
How do you justify the "God of love" to someone who ask you that? Doesn't love do no harm? Even if God isn't responsible for their actions, He created them knowing their eternal state would be damnation and pain beyond anything we can comprehend.
Ecclesiastes 6:5 - A stillborn child has more rest than he—though never seeing the sun or knowing anything
Both sides of the argument has tough issues to wrestle with, but I am hopeful there is middle ground we can agree on.
