Pro seems to be making this debate focus on the Bible instead of a philosophical approach. The debate is titled "Does Eternal Hell Contradict A Merciful God?", not the God of the Bible. "This debate examines if an infinitely merciful God can justly impose eternal hellfire for finite sins." These points seem to focus on the concept, not a specific interpretation. I will still defend the Bible in this debate, but if you still think I am unable to give reasonable answers, that doesn't mean hell and God are incompatible, just like trying to disprove the Bible doesn't disprove theism.
"Eternal, conscious torment is radically out of proportion to any finite human sin; scripture says our lives are “a vapor” (James 4:14), yet traditional hell teaches infinite pain for a few decades of failure, which clashes with God’s own demand for just, measured penalties (e.g., proportional restitution in Exodus 21–22)."
Just because life is short doesn't mean it isn't impossible to commit deadly sins:
"He that knoweth his brother to sin a sin which is not to death, let him ask, and life shall be given to him, who sinneth not to death. There is a sin unto death: for that I say not that any man ask. 17 All iniquity is sin. And there is a sin unto death" (1 John 5:16-17)
There is the sin of refusing forgiveness:
"Therefore I say to you: Every sin and blasphemy shall be forgiven men, but the blasphemy of the Spirit shall not be forgiven" (Matthew 12:31)
Following pro's logic, this would make heaven impossible since nothing we do in life would earn us heaven either.
"The Bible repeatedly says God is “rich in mercy” and “slow to anger” (Exodus 34:6; Ephesians 2:4), and that “mercy triumphs over judgment” (James 2:13); an eternity where mercy is forever withdrawn from billions looks more like judgment triumphing over mercy, undermining these core revelations of His character."
"Slow to anger" implies there is anger at some point. "Slow to anger" supports the concept of hell because God can save all punishment until after death.
Just because God has mercy doesn't mean all will accept His mercy. Everyone has the chance, but not all use this chance.
"Jesus commands us to love enemies, forgive “seventy times seven,” and do good to those who hate us (Matthew 5:44; 18:21–22); if God’s own forgiveness stops at the grave and becomes endless retribution, His actions contradict the very ethics He lays on His children, making Him say “Do as I say, not as I do.”"
We should forgive our enemies, but that doesn't mean they will be saved.
"Many who would allegedly suffer eternally (e.g., those raised in other religions, traumatized, or poorly taught) never had a clear, informed chance to understand Christ; condemning such people without end would violate biblical principles that God judges “according to the light given” and “shows no partiality” (Acts 10:34–35; Romans 2:12–16)"
God has revealed Himself to all:
"For the wrath of God is revealed from heaven against all ungodliness and injustice of those men that detain the truth of God in injustice: Because that which is known of God is manifest in them. For God hath manifested it unto them. For the invisible things of him, from the creation of the world, are clearly seen, being understood by the things that are made; his eternal power also, and divinity: so that they are inexcusable." (Romans 1:18-20)
God is just and only punishes those who truly reject Him, but those who don't "know" Him can still reject Him. No one truly misses out on learning about God.
"Hell is often justified as a “free choice” to reject God, yet scripture depicts sinners as deceived, hardened, and spiritually blind (2 Corinthians 4:4; Ephesians 4:18); punishing blindness with endless fire looks less like honoring free will and more like abandoning the sick instead of healing them, contrary to the Good Shepherd who seeks the lost until He finds them (Luke 15)."
The Bible says Pharaoh hardened his own heart:
"And Pharao seeing that rest was given, hardened his own heart, and did not hear them, as the Lord had commanded" (Exodus 8:16)
Pharaoh did not accept God's mercy. Pharaoh hated mercy. Mercy hardened his heart. God did not unjustly harden his heart. The fact that God was merciful hardened Pharaoh's heart.
"Eternal punishment has no restorative purpose—no repentance, no reconciliation, no end; biblically, God’s judgments are repeatedly described as corrective and aimed at repentance (e.g., Amos 4, Revelation’s plagues), so an endless penalty with zero redemptive function appears more like cosmic vengeance than the discipline of a merciful Father (Hebrews 12:6)."
Capital punishment has no restorative purpose or repentance but can still be just. Hell could also exist so people repent. If there were no consequences, people would feel indifferent, which God does not want.
Eternal sin requires eternal consequence because of God's justice. Rejecting the All-Powerful Being is a sin of infinite weight.
