You brought up an interesting twist Cold Steel. How would one sin against Gods active force. I am not atheist.
Jehovahs Witnesses ,JW, believe that once you learn about Jehovah and the bible then turn around and deny the bible and God word is sinning aganist the holy spirit.
Having doubts and questioning is not sinning. Some might even think they are atheist but God reads hearts.
When some one learns about Jesus then deliberately practice sin it means there is no more sacrifice left. How many times does Jesus need to die for mankind once for all sins. We are all guilty of practicing sin but thank God for prayers. Also, the big issue is when someone sins against You how hard it is to forgive your brother or sister for their sins. Forgiveness is upon congregations.
When someone talks about sin the topic of forgiveness is to follow. It changes things.
Denying Jesus means there is no hope left. But again I am human and I leave the judging to Jesus.
I heard the WatchTowers are getting worse to read.
There are churches that pamphlets are so boring it makes you want to sleep.
Some churches are like the JW,Mormons and Seven Day Adventist.
Which church did you get baptized?
