this is how i understand where we are in this discussion:
i see it as accepting that scripture is very clear about both things. therefore i accept both.
you see it as one thing you accept scripture saying, and the other thing, because you can't comprehend it, based on how you understand the first thing, you reject, even though scripture says it. and you try to justify your rejection of what it says by various means of making the scripture say the opposite of what it actually says.
i believe this to be very much, bad hermeneutic, and exactly not 'harmonization' - - imagining you have a tuba instead of an violin does not bring the violin into harmony with the fleugelhorn. what it does is ask a violinist to completely corrupt how their instrument is played. blowing into a violin is frankly nonsense.
instead the good conductor finds the tones where violins and fluegelhorns agree.
i see that you "accept both" that God "takes no pleasure in the death of the wicked and that He hardens hearts" and thus you believe double-think is better than harmonizing.
You think we must "ask why God would harden an heart or hide knowledge from another", but you do not answer that question.
My answer is based on teachings of Paul (TOP) such as the following:
TOP #25: All have sinned by breaking moral law but may be justified by God’s grace through faith in Christ’s redemption or atonement. [RM 3:9-26] The most familiar part of this passage is v. 23-24, “All have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that came by Christ Jesus.”
TOP #30: God demonstrates His love for sinners by means of Christ dying for the ungodly or atheists. [RM 5:6-11] This is called being “reconciled”.
TOP #32: God’s grace or salvation is provided to everyone who receives/accepts it. [RM 5:15-21] Paul does not explain how everyone may accept God’s gift.
Also 1TM 2:3-4, "
God our Savior wants all men to be saved and to come to a knowledge of the truth." "All" would include whomever you think God hardens or hides the truth from.
And of course there is JN 3:16, "
God so loved the world that He gave his one and only Son, that whoever believes in him shall not perish but have eternal life."
I see two ways to harmonize Scriptures such as those I just cited with EX 10:1, "Then the Lord said to Moses, 'Go to Pharaoh, for
I have hardened his heart and the heart of his officials so that I may perform these miraculous signs of mine among them... that you may know that I am the Lord.'"
1. God's hardening does not abrogate MFW in a way that prevents anyone from being saved, but rather by this means God tweaks the river of history so that it flows in accordance with His POS, causing someone to be stubborn/obstinate without condemning them to hell for that reason.
2. OT writers did not distinguish between God's intentional and permissive wills, so that IS 6:10 says, "
Make the heart of this people calloused... otherwise they might... understand with their hearts and turn [repent] and be healed." Whereas when Jesus cites this passage in MT 13:15 he changes the wording to "
For this people's heart has become calloused... otherwise they might... understand with their hearts and turn and I would heal them."
I accept this harmonization. And you?
