Nor the Holiness of God. God cannot tolerate or allow sin in heaven because of His Holiness. Excluded is anything or anyone who is not holy.
Because Mankind died with Adam, none have a righteousness or holiness of their own. None can attain heaven on their own merits due to their sinful nature, but also due to even one sin added to it. Paul in Romans agrees with King David - None are righteous, NOT EVEN ONE.
Therefore it is imperative to enter the Kingdom of Heaven through the narrow gate - that gate is Christ. For there is no other way that faith upon Christ alone and His death upon the cross paying for the sins of folks like us. There is no other way.
And if God will not accept anyone without that sheepskin, there has to be a place for immortal souls to go. And there is no other way of putting it, but that place is Hell.
It is a place where folks cannot move and burn like incense on a plate. They serve him as they were designed, but not in the presence of pure love, pure joy, and pure holiness of which God is.
Therefore, logically, those who do not believe in Hell, do not believe in the Holiness of God.
What exactly is Hell? What does the Bible say about it?
