Those who have the opportunity and don't
@Everlasting-Grace are those who deny God, notice he said those who have opportunity.
This Sin is unbelief. There not saved until there baptized.
If there refusing to be baptised with unbelief then there deliberately denying God. If there given opportunity, Such practice is sin unbelief and denying.
I don't know if they could go to hell
But I know the seed can go into a person and be removed before they've been saved.
Because the wages for sin is death.
The parable in luke says the word of God is the seed, that was in a man for a.while who experienced joy, but did not conform, so the seed was removed.
Well you have to be baptised to be saved.
Bible says so
So once again your attitude doesn't wash with me 😊
