Go, and Sin No More

A woman was caught in adultery.  (What about the man she was with, I would like to know?)

Sinless Jesus didn't accuse or condemn.  He first rebuked her self-righteous accusers.  Then He said, in essence, "I don't accuse you.  But go and sin no more."

If a couple is "caught" in fornication, what would Jesus say?  Perhaps he would say, "I don't accuse you.  But go and sin no more. "  How, exactly, does this couple "Go and sin no more?"

I see two options for them:

1. Live separately and no longer be intimately involved.  They could try dating again - not easy once the relationship has already been established on a deeper level.  Still, it is an option that is within God's circle of blessing.

2. Get married and bring into wholesomeness the relationship that they have chosen. Also an option that is within God's circle of blessing, if they are both believers.

If anyone, then, knows the good they ought to do and doesn't do it, it is sin for them.
