If you believe that the bible is God's inspired word, the subject of hell is a difficult pill to swallow.
Why would a loving, kind God send people to hell?
He doesn't. Scripture shows that anyone who suffers God's wrath does so for a reason:
John 3:35-36 says The Father loves the Son and has given all things into His hands. The one who believes in the Son has eternal life, but the one who refuses to believe in the Son will not see life; instead, the wrath of God remains on him.
As long as Adam and Eve were obedient and did not eat of the tree of the knowledge of good and evil, they had access to the tree of life.
Once they sinned, they were driven from the Garden, and God placed an angel with a flaming sword to guard the tree of life so they would no longer have access to it.
Eternal life was now no longer theirs.
Just as God had warned, they died, and through Adam all men after him would die (Romans 5:12).
By blocking access to the tree of life, God showed compassion in His omniscience. Knowing that because of sin, life would be filled with sorrow and toil, He graciously limited the number of years men would live.
To live eternally in a sinful state with its results—pain, disease, heartache, toil, and grief—would mean endless agony for humanity, with no hope of the relief that comes with death.
By limiting our lifespan, God gives us enough time to come to know Him and His provision for eternal life through Christ, but spares us the misery of an endless existence in a sinful condition.
Hell is a place where unredeemed sinners live eternally in a sinful state with its results—pain, disease, heartache, toil, and grief—which results in endless agony, with no hope of the relief that comes with death.
