God hates divorce PERIOD. There are no "if"s in that statement. What you are saying is not in Scripture.
How is it Christ-like to humiliate 3 women by divorcing them: putting them out on the streets as "used goods"(as Muslims would view them)?!
You would doom 3 women to life long poverty, and shame, and think it righteous to do so?
No! A righteous man would suck it up, and own up to his foolish decision, to get married 4 times, and sacrifice himself for them daily.
Here's what I don't understand in what you're saying: The first woman you marry is the wife period. You both are bonded together with the ordination of God. The second woman you sleep with is called adultery. There is no marriage, not in God's eyes as God is the only one that gives the OK. Marriage is not something from man first off, it is from God only, make no mistake about that.
The third woman is adultery also, you are not married but to the first. You may have a piece of paper you may have this and that, but you don't have God's say so. Period. NO IF'S, NO AND'S, AND NO BUT'S. You only have sin of adultery.
And, the same for the forth woman.
Now, divorce? You can only divorce the woman you were married to by God. You can't divorce a woman you are not married to which is woman #2, #3, and #4. You can only stop sinning by adultery with them.
Now it does say in the NT By the Lords command that under certain conditions you may divorce your spouse. But yes, it was not so from the beginning, which anyone with brains knows was the Marriage of Adam and Eve by God, NOT MAN. It is not in man's power to marry anyone except it is given to man to do so by God. But again, it can only be of one man and one woman.
Therefore polygamy is not the marrying of a man to two or more woman simply so because God in His righteousness only marries one man to one woman. The second woman or more is only the sin of adultery. And this is ordained from God from the beginning of mankind.
Abram had one wife Sarai and Hagar was Sarai's maid servant. Once again like Eve deceiving Adam, Sarai deceived Abram as she had no right giving Hagar to Abram to act as a wife in the first place. And, Abram committed adultery with Hagar, God never married them. Did God give the OK? No. Sarai did. Who was she to give orders to man? No one!
Read this carefully and you'll see Abram never excepted Hagar as a wife because He still called Hagar, Sarai's handmaid who it shows was still under the command's of Sarai. How could one wife be over another wife? They would be equal. So the only thing you have here is deception and adultery:
Gen 16:1 Now Sarai Abram's wife bare him no children: and she had an handmaid, an Egyptian, whose name was Hagar. 2And Sarai said unto Abram, Behold now, the LORD hath restrained me from bearing: I pray thee, go in unto my maid; it may be that I may obtain children by her. And Abram hearkened to the voice of Sarai. 3And Sarai Abram's wife took Hagar her maid the Egyptian, after Abram had dwelt ten years in the land of Canaan, and gave her to her husband Abram to be his wife. 4And he went in unto Hagar, and she conceived: and when she saw that she had conceived, her mistress was despised in her eyes. 5And Sarai said unto Abram,
MY WRONG be upon thee: I have given my maid into thy bosom; and when she saw that she had conceived, I was despised in her eyes: the LORD judge between me and thee. 6But Abram said unto Sarai, Behold, thy maid is in thy hand; do to her as it pleaseth thee. And when Sarai dealt hardly with her, she fled from her face.
7And the angel of the LORD found her by a fountain of water in the wilderness, by the fountain in the way to Shur. 8And he said, Hagar, Sarai's maid, whence camest thou? and whither wilt thou go? And she said, I flee from the face of my mistress Sarai. 9And the angel of the LORD said unto her, Return to thy mistress, and submit thyself under her hands. 10And the angel of the LORD said unto her, I will multiply thy seed exceedingly, that it shall not be numbered for multitude.
