Hell really exist because the word of God never lies or fails. God has said in His word that there is life after death where each and every one pays accountability of what he or she did on this earth over there. There is paradise for all the righteous who leaved holy life by following and obeying the teachings of God and there is also hell where all sinners are cast into the flaming fire where there is pain, sorrow and gnashing of teeth.
Dwoodsdawn you are right. Nobody can question God's supremacy. He said it and you only have to believe and get your reward accordingly. Do what's right n have everlasting life or do what's wrong and suffer hell fire.
