Fornication (sexual immorality)
I would like to study the context of that verse. I would like to know where in the bible you found it.
I totally agree that "going around having sex with many women," a.k.a. promiscuity, is a sin. However that concept cannot be applied to a loving relationship. "There is nothing in the mind of God that could be against a loving, sexual relationship, freely entered into, without coercion, among sincere adults." - Dr. Stayton (Baptist)
When a sexual relationship is dishonest, unloving, exploitative, coercive, manipulative, selfish or destructive of human personhood, then it is a sin. These actions in promotion of sex can be considered fornication. Did you know that the NIV Bible does not use the word 'fornication?' It has been replaced by two words: 'sexual immorality.' I think everyone would consider the long train of words at the begining of this paragraph immoral, but would you consider love immoral?
