Remarriage

Suppose your spouse left you and divorced you, and either (a) sexual immorality prompted the divorce, or (b) your former spouse died, or (c) your former spouse has married another and there just ain't no way they are ever coming back.
Suppose you had someone interested in marrying you. How would you decide whether to marry them? I've heard some suggest that even when there are scriptural grounds for a divorce, you should not marry another. I've heard others suggest that if 'sexual immorality' was a grounds for divorce, you may marry another.
What guidelines do you suggest? And why?

According to Jesus (Matthew 19), divorce does not end a marraige. Only two things do: adultery and death. After adultery, the couple could be reconciled (as you see with Hosea), but the original covenant has been broken. Paul says that, in the case of a believer being married to an unbeliever, that if the unbeliever leaves the believer then the believer is "not under bondage", (I Cor 7:15) which I take to mean free to remarry.

I see marriage as being like a contract. Once the contract is broken by one party, then the second party is under no obligation to remain in the contract-- it was already broken. So one can join in another contract, in contradiction to the first, because the original is null and void.

However, again, the crux of the matter is that divorce doesn't nullify the covenant one made before God. But adultery (or remarriage) does). So for my congregation who are divorced, but neither of the couple has remarried, I strongly encourage reconcilliation, or celibate patience for God to reconcile. But if one of the couple remarries, then I can give freedom to the other to remarry, if they choose.

I know this is in opposition to most Christian viewpoints, but the one side seems too harsh in comparison with Jesus' actual teaching, while the other side seems to just be ignoring Jesus' teaching.
