NOT scriptural to toss out all the other scriptures that say differently. You assume "dead" means condemned to hell? Could it possibly mean, based on other scripture, unfruitful, inactive, etc.?
Do you imagine you will be saved by a dead faith?

You assume "dead" means condemned to hell?
According to Scripture it means "as the body without the spirit is dead". Do you think you are perserving to the end by separating faith from love?
