(Proverbs 6:35 KJV) He will not regard any ransom; neither will he rest content, though thou givest many gifts.
This is part of a warning involving our interpersonal relations. If you look back a few verses this involves someone who has committed adultery. Solomon then proceeds to explain why there will not always be easy fixes.
Adultery involves the ultimate betrayal and violation of trust. The sexual relationship was designed by God as a one-to-one covenant. It was to be life long. I know that the modern attempt to water marriage down has a vow that says, “As long as we both shall love,” but the one that God endorses is “as long as we both shall live.”
So? Some sins are avoidable. There are no excuses. You may find some type of forgiveness from the people you have wronged but you will never be able to restore the trust again. Live in righteousness.
