What you are missing is that that faith, that pouring of the Spirit, that calling to salvation is available to all.
Yes, Jesus said that no man comes to the Father unless the Spirit draws him - and Jesus made clear that that “drawing to the Father” is there for everyone to respond to. “Come unto Me all that are weary and heavy laden, and I’ll give you rest.”
Yes we cannot save ourselves - that is only accomplished through the life, death, burial, and resurrection of our Lord Jesus Christ - but we have to respond. Jesus’s sacrifice is sufficient for the salvation of all mankind. “For God so loved the world” means just that - the whole of humanity.
The Bible is filled with the command “choose this day Whom you will serve”, “follow Me”, “resist the devil”, “come unto Me”. None of these commands make sense if we do not have the ability to respond ourselves to God’s grace.
God giving us the freedom to grasp onto to His lifeline of salvation in no way takes away from His glory or sovereignty. He sovereignly chose to give us the ability and freedom of our wills to accept or reject Him.
If we don’t have that freedom, then how is it loving Him if we choose Him since we were pre-programmed to do so? That makes no sense to me.
[The] “ ‘drawing to the Father’ is there for everyone to respond to.”
The gospel message is a limited time offer. Overlooking this has resulted in one of the logical fallacies of Calvinism when it comes to so-called “irresistable grace”. We are told “now is the accepted time” and “today is the day of salvation”.
After death and, at least for some, even in this life, there comes a time when people who harden their hearts to the truth no longer have this offer of salvation to respond to.
So we see there are some who CANNOT believe. This is not because they never had the opportunity to repent and believe. Rather, it is because they refused to do so until it was too late.
Because we may not know who has hardened their hearts to this point, we must continue to preach the Gospel to all who will listen even if only a small percentage repent and believe.
