There is biblical reason for divorce and its the topic of thread. Why not remarry another if adultry was the cause for divorce in one's first marriage?
There is not a biblical reason to go against one's own vow and marry another while our spouse is alive.
You vow "Until death do us part" not "Until divorce do us part".
I'm sorry, but you are still married in the eyes of God until your spouse dies.
And if I were the adulterer? What then? I am now forgiven...but life is often more complicated than can be easily explained.
