I am a 7th Day Adventist and we only believe in what the Bible says. This is what the Holy Scriptures say about Hellfire:
-Not one single soul is in hellfire today(2Peter2:9)
-Sinners will be cast into the hellfire at the great judgment day at the end of the world(Matthew13:40-42)
-Both the wicked and the righteous are in their graves "sleeping" until resurrection day(John5:28,29;Job21:30-32)
-The wicked will perish, burn up be destroyed in the fire(Job21:30;Romans6:23;Malachi4:1;Psal...
-Hellfire will go out, and there will be nothing left(Isaiah 47:14)
-Only ashes will be left(Malachi4:1,3)
-Real live people will enter hell in bodily form and will be destroyed both body and soul.(Matthew5:30;Ezekiel18:20)
-the devil will also be cast into the fire(Ezekiel28:18,19)
*The purpose of hellfire is to destroy sin and the devil and to make the world safe for eternity. Eternal hell would only perpetuate sin and make eradication of sin impossible.
Eternal hell is NOT God's plan.
So you choose, either believe what the Bible says, or continue believing what Christians have been taught for hundreds of years; even though is not founded on the Bible.
