—Mat 5:32 But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.—
That was a tough one for me. My wife and I were both divorced before. We had both been abandoned by our spouses when we met, about 15 years ago.
Wonder if we are forgiven.
JK.
Based on the scripture you cite and your situations, I think it is obvious that being abandoned means the covenant was broken by the other spouse.
A covenant is a sort of a contract. When broken by the other party, the offendended party is released from it and is free to remarry.
