I understand your tack in this lesson, but the Scrpture quoted and Edwards' discourse all have the saveable sinner in a crowd whose God's omniscient foresight of all future outcomes sees there are many that will never respond. Unless there is a Purgatory (and I fully doubt it) the account of Lazarus and the rich man in Luke 16, wherein Jesus illustrates a Hellish outcome (and I believe this is an actuality) we see no hint that either He or the Father any longer have a loving compassion for the tormented sinner. I will not be easily convinced that God has any love left for the person who yields up his physical life, expecting annihilation of the soul and spirit rather than an excruciating eternal death. The basis is the indication from Genesis 6:3 (AV):
I do not know where I said anything that made those in Hell to be loved by God, especial if love is to be considered an attitude resulting in action. From the beginning I argued that God hates/abohors sinners and who are the objects of His anger an wrath, as were (and without faith would and can be), but yet loves them, thus is not willing that any perish. However, as I also stated God "will send the lost to Hell and "despise their image" (Psalms 73:20)" when He awakes in judgment of them.
And I agree with you. I was just presuming that your thesis included candidates still alive. But even some of those might have been by God, through His unique faculty of foresight, excluded (not knowable by us, their acquaintances) from further efforts even by God Himself.
Please know that I am not contending with you regarding our ongoing witness to those about us even though we might suspect their adamantine unreachability. We do the proclaiming, they do the repenting, and God does the saving. Like Paul Revere, who cried out the warning, but did not stop to debate about it. Having alerted one district, he just went on to the next. How the hearers dealt with the knowledge was not within his purview.
