James says that if you sin one sin, you are guilty of all. Because of this, all sins are capital sins.

You are still talking about the New Testament: the Bible is one.
Do you believe that Jesus Christ is our Messiah and Saviour?
Best regards.
Thank you for recognizing that the Bible is one. This means that you recognize James 2:10, that you are guilty of being an atheist even though you never practiced atheism.
You atheist, you. You deserve to die.
