So do you believe that not all those for whom Christ died will actually be saved?
The scripture do say, not all shall become saved, but nevertheless all are equally welcomed by the Gospel to be saved.
The point is,
GOD so loved the world, and
the Son takes away the sin of the world, not of some individual's only.
Those unsaved are due to, instead of coming into the Light, they rather loved darkness and remain.
The parable is about a man who makes a banquet and invites his reputable neighbors and friends.
But none turned up and some made excuses that they had some personal matters to attend to.
Therefore the man told his servants to go to every street corner cum alley and invite every bunch of non reputable nobodies.
He made sure that his house was filled and packed, that none of the earlier invited guests will be able to get in.
Now, equally the first invitation was to all whom he knew, and then only second he gave out to those he knew not.
Who is to be blamed when one is not saved, or one is saved but not ready and left behind, or in the end one's rejected as workers of iniquity/lawlessness?
How could He be satisfied, if just one for whom He had given His life ended up unsaved?
Indeed, because in some of the parables he gave, speaks about also the lost, and due to this at the end He cried.
He even prayed to the FATHER about Judas Iscariot, where He tried to keep the 12 saved, but sadly 1 had to be lost.
If it did not matter to Jesus about Judas' lost of his own doing, He wouldn't have prayed to the FATHER.
We are told several times that the reason Jesus came to earth was to save sinners, not just to make salvation a possibility:
Salvation a possibility to the whole world, but there's a protocol to believe, follow, be saved and stay safe in the race until our time is up.
“This is a faithful saying and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief.” (1Ti 1:15 NKJV)
Paul was a violent persecutor of the church, but even a man like him can also be saved and finished the race.
We've been discipled that,
For what we seem impossible but for GOD all things are possible.
Shalom in the name of Jesus Christ
