When one claims a good and loving God would not allow anyone to suffer in hell, explain first that God is foremost holy and righteous, and justice is one of his qualities. Then, explain that hell is an option, for, upon simply believing, deliverance occurs.
God’s divine qualities are evident through all of creation, so man is without excuse. We have evidence through God’s word and nature for the existence of God and Jesus, as well as salvation. Yet, it is pride preventing us from believing.
God sent his sole son to earth, in the form of flesh, to live as us and share with us the truth of heaven and hell, of salvation. Jesus committed no trespasses, but was crucified on a cross as punishment for our transgressions.
