And unto the married I command, yet not I, but the Lord, Let not the wife depart from her husband: But and if she depart, let her remain unmarried, or be reconciled to her husband: and let not the husband put away his wife. (1 Corinthians 7:10, 11 KJV)
Jesus mentioned the fact, that those who put their wives away, and marry another, sin. Those who seperate for reasons other than sexual immorality, have the chance to be reconciled back to their husbands and wives.
For this cause shall a man leave his father and mother, and cleave to his wife; And they twain shall be one flesh: so then they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. And he saith unto them, Whosoever shall put away his wife, and marry another, committeth adultery against her. (Mark 10:7-9, 11 KJV)
Whosoever shall divorce his wife, and marry another is in sin, and has committed adultery. The problem lies, in committing adultery. How can you commit adultery against someone you're supposedly not married to? Simple. You actually still are married to her, and that's how God views it. It has not been "put asunder," as they believe it has been. They are still cleaved. So to do something with someone else, to marry another wife, is absolute sin. It is adultery.
And the firstborn said unto the younger, Our father is old, and there is not a man in the earth to come in unto us after the manner of all the earth: Come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father. And they made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose. And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father. And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose. Thus were both the daughters of Lot with child by their father. And the firstborn bare a son, and called his name Moab: the same is the father of the Moabites unto this day. And the younger, she also bare a son, and called his name Ben–ammi: the same is the father of the children of Ammon unto this day. (Genesis 19:31-38 KJV)
Sin. Not censured. Please tell me how it was perfectly okay for Lot's daughters to get him drunk, so they could have sex with him.
When thou art come unto the land which the Lord thy God giveth thee, and shalt possess it, and shalt dwell therein, and shalt say, I will set a king over me, like as all the nations that are about me; Thou shalt in any wise set him king over thee, whom the Lord thy God shall choose: one from among thy brethren shalt thou set king over thee: thou mayest not set a stranger over thee, which is not thy brother. But he shall not multiply horses to himself, nor cause the people to return to Egypt, to the end that he should multiply horses: forasmuch as the Lord hath said unto you, Ye shall henceforth return no more that way. Neither shall he multiply wives to himself, that his heart turn not away: neither shall he greatly multiply to himself silver and gold. (Deuteronomy 17:14-17 KJV)
Clever retort, but it's not saying "only one piece of silver and gold". We know we are not to love riches in that way, God's word is plain about that. This would fall in line with heaping treasure together for yourself. The kings were not to multiply wives themselves, at all. Why? Because that's Polygamy, that's sin. Howbeit, you don't see it as sin. Therefore, I am not sure if you can see what i'm seeing, so let me try to explain. As I said, polygamy is in there. Simply because it does not have the word "polygamy" there, does not mean it was not included. Multiplying wives unto yourself, is one of many times it is mentioned. Jesus also mentioned it, by calling it adultery to "put your wife away" and marry another. You have not really put your wife away, you are still married in God's eye's, and thus you have committed adultery.
God did deal with Polygamy. If it did not matter, Sarah's handmaid would never have had to leave. But Sarah, being the first wife, wanted the handmaid and her son out of the house. Sarah is the first wife, she is entitled to rights as the first wife, which no other woman can encroach upon. Abraham is a father, would he have so easily given up his son? No. And God honored the request of Sarah, by telling Abraham to cut her (the handmaid) loose. But God promised Abraham that though sent out and away, the child was not to be forsaken.
The Bible also talks about Deacons, and bishops being only the husband of one wife.
A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach; Likewise must the deacons be grave, not doubletongued, not given to much wine, not greedy of filthy lucre; Let the deacons be the husbands of one wife, ruling their children and their own houses well. (1 Timothy 3:2, 8, 12 KJV)
I find it interesting, they were to have only one wife, and not given to filthy lucre, the same way the kings were not to multiply gold and silver, and were not to multiply wives to themselves.
Where have I claimed to have a closer relationship with God, more than what you refer to as "spiritual giants"? I have said, we have the scriptures. We study them (should) daily. We should be men after God's own heart. What? Think you, that because they talked to God, that means God pointed out every single flaw to them? God only judged them on the light they only had.
The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished: But chiefly them that walk after the flesh in the lust of uncleanness, and despise government. Presumptuous are they, selfwilled, they are not afraid to speak evil of dignities. Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children: (2 Peter 2:9, 10, 14 KJV)
The wicked are reserved unto the day of judgement.
Simply because God did not alert one to their sins previously, and they were not %100 perfect, does not mean God sanctions sin. As we increase in spiritual knowledge, there is a constant growing.
Just because God did not immediatly wipe out David, and everyone else for their polygamy, does not mean he never cared about it. The Word of God shows that God very much so does.
Hope this helps!
