Matthew 5:32b …and whoever marries a woman who is divorced commits adultery.
(See also Matthew 19:9)
If your wife was previously divorced, you’re in a perpetual state of adultery.
I’m not sure what to recommend to those in this situation. Please don’t attempt to divorce your wife to free yourself from this sin. We’ll show later that God hates divorce (which could be also considered a sin). This is truly being between a rock and a hard place.
