In Acts 15:19-20, James writes to the church, "Therefore it is my judgment that we do not trouble those who are turning to God from among the Gentiles, but that we write to them that they abstain from things contaminated by idols and from fornication and from what is strangled and from blood." I looked the word "fornication" and in the Greek meaning of the word it means idolatrous harlotry and adultery. Now, I have had my experience with having sexual relations with a girl before the ceremony vows. I never felt right about it, and I'll submit here to God that yes, it is a sin, because I had convictions to quit this behavior and I felt better when we weren't doing that. But I don't see how it is a form of fornication according to the definition. Is it a sin because it is immoral instead? I really don't see the connection with fornication. If anyone can shed light on this it would be helpful. Thanks.
