Irresistible grace doesn't teach no one resists the Holy Spirit, but that those who are saved don’t resist it all the way until death. Remember, John Calvin didn’t come up with the TULIP. It’s been around since around 1900 or so. I don’t think anyone knows for sure who came up with TULIP. Irresistible grace is not a perfect name for it, but you can’t spell TULIP TULEP. I’d guess that’s why they used Irresistible Grace for that acrostic.
Another name for it is effectual calling. Notice how effectual the Spirit’s drawing was when you received Him. That’s what we teach. When He draws ppl, they come. They aren’t forced to be saved, neither does He drag them kicking and screaming against their will. The Greek word used is ‘helko’(pronounced hel-koo-o) and it means to literally drag off, lead, impel, draw with an inward power.
It is also found in John 18:10 when Peter drew(helko) his sword. Did the sword say no when Peter drew it, or did Peter effectually draw it from its scabbard?
It is also found in John 21:11 when Peter drew the net to shore. Did the net say no when Peter drew it, or did Peter effectually draw it to the shore?
It is also found in Acts 16:19 when they dragged(KJV uses drew) Paul and Silas to the market place. Did they say no or did the mob of ppl effectually draw them to the market place?
It is also found in Acts 21:30 when the ppl dragged(KJV uses drew) Paul out of the temple and shut the doors behind him. Did Paul say no when the ppl drew him out of the temple, or did the ppl effectually draw him out of the temple?
Again, this doesn’t mean God drags us to Him kicking and screaming against our wills, but teaches us when He draws them, He effectually draws them to Himself.
