Trixie,
Yes, indeed, Yeshua or Jesus has indeed paid the price for everyone's sin, and any and every one who so choses can walk away from death and destruction. Moreover, any that do make that choice, for life and truth, whatever "theology" they espouse, whatever they know or don't know about what Jesus did for them, the "sin" associated with their ignorance is redeemed and does not kill them. But life for humans involves free will, and the first thing Yeshua bought for us all is the choice, the freedom. Those who take that freedom, and stay in or walk back into spiritual captivity, in this case, denial, are still free to do so, which means that they get what they are asking for, the consequences of that choice, which is death, delusion, whatever we are told are the consequences of certain behaviors. "Behold the goodness and severity of God."
You know the history, Trixie. People want freedom more than anything, and do not want to be forced into loving God, or avoiding evil. The devil sets out his temptations, they like what is offered and run away from any effort to tell them that they are being had. The Thessalonian verses that tell how God Himself sends out the spirit of delusion to those who will not "love the truth." are in the NT. I'm warning as many as I can that schools are bad epistemology, according to God, and that choosing to let schools be one's way of learning the truth is basically hating the truth. At least, it is if you know anything about God. But, people are free to shake their heads, and write the prophet off, because schools are convenient, or something. Instead of searching out the truth of the matter, loving the truth, they rationalize the schooling option. It's a fatal choice, not getting to the truth of the matter. Not learning how to get to the truth of the matter. And God sadly shakes His head, but can do nothing without taking away their choice. And so, He lets them go.
I didn't write the book, Trixie, I only read it and asked it's reputed Author to explain difficult verses. That's good epistemology, that's loving the truth. Did I like what I learned? Of course not. But changing one's mind when we discover that "our ways are not God's ways" is highly recommended, so I did. Millions do have a different view of God, and their life has little to commend it.
Peace.
Stephen
