Our sin is deserving of eternal punishment because of who we have sinned against; a holy, omnipotent, perfect, eternal God. Punishment satisfies justice. Hell is justice served, according to God.
Staying out of hell is a matter of choice. God provided His free gift of salvation to all who would repent and receive Him as Lord and Savior. Everyone has the opportunity.
It’s only the grace of God and the blood of Jesus that redeems us. Our part in redemption is our faith in Jesus Christ. Faith is a requirement for salvation, and there will be no faith required once a person sees hell. God gave the most precious thing He could give man to redeem his soul from hell; His own Son!
Do you truly understand the punishment that awaits every one who rejects Jesus Christ?
