A quote from Brother Mark
In every case but one (Luke 16) Jesus used the word Gehenna when talking about judgment yet Paul never used the word Gehenna. (nor anyone else except James how used it one time) Paul only used the word hades one time and then he said that it had no power. "Death, where is your sting? Hades, where is your victory?" 1Cor 15:55.Our view of Christ and his teachings definitely grows as we mature in the Lord. The calvinist still preaches that only those that believe in Christ IN THIS LIFE go to heaven. The Arminian the same. Others that preach differently preach a message that neither Paul nor Jesus taught.
Gehenna was a literal place and no where else in scripture is a literal place changed to mean something in the spiritual.
Were Jesus and Paul teaching the same thing?
