Technically,
@Presby02 said "I would still attempt to save them despite themselves. And would if I could." to which you replied "God doesn’t 'attempt to save' he either saves or doesn’t save". Both what Presby02 said of HIMSELF and what you said of GOD (representing monergistic soteriology) are accurate statements. It is not reasonable to conflate Presby02 with God ... they are not even close to EQUALS. So Presby02 in his ignorance of eternity can attempt to save all, confident that GOD will "show mercy on whom He will show mercy". God, in contrast, "knows the end from the beginning" and has/is/will foreknow, predestine, call, justify and glorify "whomsoever" as He wills.
