sexual immorality -IS SIN full stop.
your sinning against GOD .
as with ANY SIN God can and wills to set people free . and i testify in the name of Jesus he does so .
and then we go on to do it no more .
I agree, sexual immorality is sin,
full stop.
But where I think we might start quibbling is over what exactly falls underneath the "sexual immorality" umbrella.
The problem is - people talk in such vague generalities - and often that leads to problems. For example, let's say I were to ask "Is masturbation sexual immorality?" I'd venture to say that a lot of people would say "yes". Heck, that's what I was taught as a kid.
But is it...really? In and of itself?
When I was a little kid and I discovered that bumping into a wall felt good, and went to town with that void of any association with sex, was that "sexual immorality"? A few weeks back my 7 year old clearly had figured out something similar and told me "This feels good". As uncomfortable as that might be for me and for me to tell them "I'm sure it does. But that's not something to do around other people" - are they being sexually immoral?
I think you'd have a hard time making that case - and if ya even tried - I would totally disagree with you.
So clearly, masturbation in and of itself isn't "sexual immorality" - so then what is? Is it the thoughts that make the difference?
Usually at this point people bring in Matthew 5:28. "
But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.". That seems like a reasonable way of granting the kid the innocence of not knowing what they're doing, but allowing you to condemn them once they get older for their impure thoughts and it becomes "sexual", right? lol
Ok, let's say we go with that. Well, back when I was a kid going through puberty, I never fantasized about actual people. I never looked at Susie across the classroom and fantasized about her later at night. To me, that always seemed kinda creepy and violating. After all, I might need to ask her a question the next day about homework or something, and the idea that I'd been fantasizing about her would just make that weird.
Rather, my fantasies were mostly just imagery that would be invented in my head. Faceless forms with body types that appealed to me, in scenarios that I liked. So yeah, there was a "sexual" component to it insofar as I was thinking about "sex"...but is that "looking on a woman to lust after her"? Is that a woman? If you think "yes", point her out to me. Where is she? What's her name? Is an invention of my mind created in the moment to achieve an end - and summarily forgotten about the instant after it's finished - a "woman" I can look upon with lust?
IMHO, no.
So, what are we left with then? I'd say, what Jesus said. "Looking upon a woman with lust". But the way I interpret that (clearly) is not the same way a lot of other people want to.
Now - as far as inappropriate content goes - yeah - it's sin. Nobody is arguing that. But going back to the original post - is it "cheating"? I think that answer is just as nuanced a the one I gave above. It depends on the situation and the expectations of your partner.
Something does not need to be "cheating" to be a sin.
