Yes it is. You ask BitNow, I'll bet he/she says questioning doctrine is a sin.
"
The fear of the Lord is the instruction of wisdom; and before honour is humility."
- Pro 15:33
"
By humility and the fear of the Lord are riches, and honour, and life."
- Pro 22:4
Best regards.
So, that's a "yes"?
You need to ask a question to have an answer.
What is your question, maybe I can help you.
Religion caused wars,the worst thing with human were done in the name of religion( from ancient times till now) and we are all witnesses how someone is using religion in his own interest. Atheists simply don't believe in nothing they live in the world that rounds them, and they follow science
They don't follow science: atheism is a sin and science comes from Wisdom witch is acquired by fearing the Lord.
If you are a sinner you need to be forgiven before fearing the lord again to find wisdom and to follow science.
Atheists are sinners: what we need to understand is if they are doing it on purpose (capital sin) or they are just ignoring the fact that they are walking on Earth sinning (minor sin).
The fact that I'm facing this sin with you is the proof that I'm involved as well.
Best regards.
