Lance, I feel like you are a pharisee, trying to stir up trouble with your questions of divorce but I will answer anyway :-)
I don't think divorce should be illegal for the same reason God allowed Moses to grant divorces - it isn't good for society. Back in the day (of Moses) men weren't divorcing their wives but were making their lives miserable because their hearts were hardened against them. They were being mistreated and abused instead of being divorced. That isn't good for society or a good illustration of God's love for his church.
So just as marriage is for the benefit and protection of women and children, in a very sad way, so is divorce. If we didn't have sin in the world, we wouldn't have that problem, but we do - so we do.
But I do think it is too easy to be divorced in this country. You may disagree, but I don't think it should be easy.
But moving from legality to church issues, I think the church is way too soft on divorce. Yes, it has become common in our society, but that doesn't mean God's view on it have changed. I think the only church accepted reasons for divorce should be those that are in the scripture. And the Bible does clearly lay out times when divorce is acceptable - never good, never what He intended, but acceptable.
In Matthew 19:9, Jesus says
"And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery."
My Strong's concordance translates that word "fornication" to porneia, which is defined as
1) Illicit s*xual intercourse (adultery, fornication, h*mos*xuality, l*sbianism, intercourse with animals, s*xual intercourse with close relatives, s*xual intercourse with a divorced man or woman.
2) The worship of idols
So apparently fornication is grounds for divorce. Another example of acceptable divorce comes up in 1 Corinthians 7:15 when it states that if a believer is married to a non-believer and the non-believe "wants out" that they are no longer bound.
My point here isn't to dissect every account when the Bible talks about divorce, it is that the Bible does talk about divorce. We don't have to use our minds to reason when divorce is okay and not okay, God tells us. And for most reasons, it isn't. And when it isn't, it is sin.
So just like I am not going to say homosexuality isn't a sin when I think the Bible says it is, neither am I willing to say that divorce isn't a sin in cases when I think the Bible says it is, even if if is unpopular to do so. I know that I don't make the rules, He does. And I think the church needs to do a better job of going back to the Bible as the basis for its standard of right and wrong.
But, and I think this is a big but, I hate to get so caught up in discussing what is a sin and what isn't a sin that I miss the whole point - forgiveness. I think it is important to define sin, because without knowledge of our sin, we can't repent, we can't ask for forgiveness. But the point is not the sin, the point is forgiveness. I said in my last post that my whole reason for living is to illustrate the gospel. The gospel is all about the grace of God. He wants us to live in his will because He loves us and wants the best for us. But He knows we can't do that on our own. That is the whole reason He sent Jesus. Repairing lives is what He does best. He wants to work miracles in our lives and restore them. God wants to forgive us of all our sin, that doesn't exclude homosexuality, that doesn't exclude divorce.
Since it all comes back to the Jesus, I feel like it is fitting to end with a verse about Him, you will probably recognize it:
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him.
