Divorce has been a long long problem. It's not something that is recent.
We should, in Bible studies, be able to come to some determinations about law as it relates to divorce. When God says, in the law, whatever law, not to do something, then the carnal or sin nature of man resists that law. This particular resistance that often results in divorce starts with the law against lust. How does that operate?
Jesus tells us clearly "how" adultery, which is assuredly connected to divorce, starts. It starts first with sin thoughts of adultery. Then "words" of adultery and ultimately with the deed, and the after effect is divorce. Matt. 5:28.
We can take this same principle of the law and apply it to any particular societal ills or sins that we see in the world. The world of flesh men, carnal minded, non legal, not even possible to be legal people, and see that it operates through the lust of the flesh, the lust of the eyes and the pride of life. 1 John 2:16 speaks directly to the 'path of darkness' upon which sin sprouts, takes root, and eventually blossoms the dead end results. No flesh is immune from this working. Not even the flesh of believers.
The path to sin is also correlated to first sin thought, then sin word, and eventually the full on deed. But the impetus, the kernal of sin starts in the realm of evil thoughts. Just as Jesus pinpoints for us in:
Matt. 15:19-20 and Mark 7:21-23
People can claim their innocence in not divorcing, but the reality is that more than likely every last married person has lusted as a result of sin indwelling the flesh, evil present with them. They may appear "legal" on the outside, but nobody really is legal in the flesh, regardless. Some keep it in check. That's all that can be said about it. But evil is an intimate part of every person's internal conscience. God has made us this way, setting before us, INSIDE, this natural knowledge. Believers can claim they are only good, but in that claim they only prove the evil within them made them LIE.
Science, in birth control, has fostered the bed of adultery and baby killing, adding even more fuel to the fire of divorce. And this results in entire societies being ripped to shreds. But even these works existed in the O.T. as shown when people sacrificed their children by fire to the god, Molech. A brass bull standing on mans feet, holding a laver which would be heated red hot, and the baby tossed in, alive, burned for sacrifice. Just as utterly vile, if not moreso, than abortion.
