Your point presupposes that God intended Universalism all along but failed to get it done.
It doesn't presuppose, it simply poses the question.
God could will for all to be saved, but only for those who meet his conditions to achieve it.
If God willed for all to be saved, but only those who meet the conditions are saved, then God's will does not obtain. That may very well be the case. Oddly enough, the way you just phrased that presupposed universalism and concluded that God failed to get it done.
But, these conditions are part of my question. What are the conditions? Consciously confessed faith? If those are the conditions than all of those persons I mentioned above will perish, e.g. OT folks, children, the cognitive impaired, those who never heard the gospel, etc. If God willed that all be saved, then God also guaranteed that many would not be. That's not consistent.
If all will be saved, there is no point in preaching the Gospel at all.
I am not convinced all will be saved. I am not convinced only confessing Christians will be saved. But more than anything, I am not convinced that eternal damnation is the gospel we preach. If hell is remedial, do we stop preaching salvation because it's not eternal? Is a hell of a million years something to look forward to?
But, I get it. What is salvation if we aren't being saved from something? Well, we are. We are being saved from condemnation before a just and righteous God, a condemnation which applies to all of us, without exception. The question is not "Are we being saved from something?" The question is, "Who will be saved." And my point is simply, "We don't know. But, we presume too much if we are certain it won't be all."
You seem to place the efficaciousness of salvation on faith in Christ. I place it on grace through Christ. Those who have faith in that grace will be saved. That I trust. But, I don't put limits on God's application of that grace that has been secured through Christ.
Well if we go by what Jesus said, it's very clear.
You know as well as I do that there are many passages for and against. You seem to think the scriptures are abundantly clear on the subject. I disagree, as I stated. As I said, I am agnostic concerning the amount of people who will eternally populate hell, if there be any. I don't declare universalism to be true or false, because I don't think it is as clear as you do. I don't condemn you for holding that there is a number that will be condemned forever. Do you condemn me?
