Hi Comm.Arnold,
Don't you understand, yet? God was describing abominations, for which He will eventually destroy you if you participate in them?
Jesus did explicitly forbid 'multiple women', when He said
it is adultery to look with desire upon a second woman.
The Old Testament is full of God's unwilling patience and tolerance towards Israel (old Israel), and Judah, for abandoning their first love - God Himself.
He destroyed those who persisted in idolatry, because He had wanted their whole hearts to embrace His whole heart, solely.
Exodus 34:14 '... the LORD, whose name [is] Jealous, [is] a jealous God...'
This is the picture of an Husband, which you are to take to heart - to be a man who both gives to, and desires exclusive love from, your spouse.
There are only two worship systems in this cosmos: the worship of God and the worship of self, aided and abetted by Satan's powers.
What you are expressing here, is pure fornication - the heart of an idolater. You are demonstrating a total lack of understanding of the issues which God brings to us in His word, of which you should be making a study for the rest of your life, whether you marry or not.
God's decrees are
Makers Instructions. He is informing you of the kind of marriage which He approves, and blesses, if so conducted.
You really need to wake up, spiritually, and give your life to God with all your heart, and stop your friendship with the world while you can.
In the New Testament, the picture is even stronger, with Jesus Christ laying down His life for one Bride, the Church, and sending the Holy Spirit to baptise believers into just one body, receiving His own very life as their reason for being and power for living.
During His earthly ministry He returned marriage to Eden, (Matt 19), and restated 'one man one woman' was what 'He who created them' had intended. If we are to take the apostles John and Paul's words to heart, too, then
'He who created them' is none other than Jesus Christ. What I'm saying is,
He knew what He was talking about. He was, also, referring to mankind having been made
male and female, in God's own image.
Deuteronomy 6:4 Hear, O Israel: YHVH our ELOHIYM is one YHVH:
Polygamy gives a picture of a man whose heart is divided, who is incapable of giving himself
whole-heartedly in love to only one, (as God does), which He pictured for us in several marriages in scripture. In so doing, Elohiym showed that He understands what the women go through, when they have to share a husband. God also shows us in the New Testament, that He has no intention of putting HIS Bride, through those agonies.
James 1:5 If any of you lack wisdom, let him ask of God, that gives to all [men] liberally, and upbraids not; and it shall be given him. 6 But let him ask in faith, nothing wavering. For he that wavers is like a wave of the sea driven with the wind and tossed. 7 For let not that man think that he shall receive any thing of the Lord. 8 A double minded man [is] unstable in all his ways.
Comm.Arnold, if you are willing to adopt God's viewpoint on these matters, you will be blessed in your marriage (to one woman) beyond anything you imagine possible, (because marriage is far more than the marriage bed), but if you continue with your unregenerate attitudes, you will reap corruption. If you keep sowing to the flesh, you will prove the truth of the apostle's observation.
Galatians 6:7 Be not deceived; God is not mocked: for whatsoever a man sows, that shall he also reap. 8 For he that sows to his flesh shall of the flesh reap corruption; but he that sows to the Spirit shall of the Spirit reap life everlasting.
In fact, it may already be that you are reaping a foretaste.
God is warning you.
Don't kid yourself that what God used in a previous era, (polygamy), was God sanctioning multiple wives
for Christians. Polygamy existed amongst the Hebrews at a time they could
never, in their hearts and lifestyle, be free from sin (as we may be), because Messiah had not yet come.
Once Messiah came,
and the Holy Spirit was poured out to enable men and women to 'live godly', we are without excuse if we go ahead and set up our lives around 'flesh', instead of the Spirit.
There is a purity of body which Christians experience when they manage their affairs according to God's word, and the leading of His Spirit. The only way you will experience that purity, is by repenting from worldly attitudes, and receiving from God, a new heart and spirit.
1 Corinthians 7:
1 Now concerning the things whereof ye wrote unto me: [It is] good for a man not to touch a woman. 2 Nevertheless, [to avoid] fornication, let every man have his own wife, and let every woman have her own husband.
28 But and if thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Nevertheless such shall have trouble in the flesh: but I spare you. 29 But this I say, brethren, the time [is] short: it remains that both they that have wives be as though they had none; 30 And they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not; 31 And they that use this world, as not abusing [it]: for the fashion of this world passes away.
32 But I would have you without carefulness. He that is unmarried cares for the things that belong to the Lord, how he may please the Lord: 33 But he that is married cares for the things that are of the world, how he may please [his] wife.
34 There is difference [also] between a wife and a virgin. The unmarried woman cares for the things of the Lord, that she may be holy both in body and in spirit: but she that is married cares for the things of the world, how she may please [her] husband.
35 And this I speak for your own profit; not that I may cast a snare upon you, but for that which is comely, and that ye may attend upon the Lord without distraction.
As far as this post from you indicated, you still have no idea what 'the main objections are', because you are not looking at your life from God's point of view. While you look at it from your point of view, constantly trying to figure out what and how much you will get out of your choices, you will continue to go round in circles. The way out of that endless loop is the cross. Give up the fleshly struggle, and yield your whole life to God.
Do it now.
As you begin to grow up in God, being led by Him in all your decisions, your life will simplfy enormously, and bloom according to His will, but that will require you to mortify the flesh. Romans 8:13
Ephesians 5:25 Husbands, love your wives, even as Christ also loved the church, and gave himself for it; [Note

ne husband one wife]
Ephesians 5:28 So ought men to love their wives as their own bodies. He that loves his wife loves himself. [Note: one husband one wife]
Ephesians 5:33 Nevertheless let every one of you in particular so love his wife even as himself ...' [Note: one husband one wife]
