Ok, may you're not understanding my point. We both agree, according to your position there are those who are the unelect. They were such before the foundation of the world. Ok now, imagine that a mother is carrying a baby who was (before the foundation of the world) unelect. The baby's status doesn't change with age. It was unelect, so wheather it dies at 88 or at 8 that person will go to hell. How is this unavoidable?
You have no understanding of another person's relationship with God.
We just live in the present, only God knows what tomorrow brings.
For example, all the days ordained for us were written down in God's book before they came to be.
God has predetermined the day of our birth and the day we will die.
So if a child dies as an infant then it was their time to die and they will be with God.
But if the child grows into an old man and never confesses belief in Christ, they will die and go to the fire.
Everything God has foreknown and determined from the very foundation of the earth.
Psalm 139:14-17New King James Version (NKJV)
14 I will praise You, for I am fearfully
and wonderfully made;
Marvelous are Your works,
And
that my soul knows very well.
15 My frame was not hidden from You,
When I was made in secret,
And skillfully wrought in the lowest parts of the earth.
16 Your eyes saw my substance, being yet unformed.
And in Your book they all were written,
The days fashioned for me,
When
as yet there were none of them.
17 How precious also are Your thoughts to me, O God!
How great is the sum of them!
