You are correct sir. Disobedience will never...ever...ever bring God's best and could yield a lot less.
But, some people, for whatever reason, determine that certain things are disobedience when they are not. For example, many people believe because of the prohibition found in Acts 15:20, that it would be 'disobedient' to receive a blood transfusion.
So, they don't because they don't want to be 'disobedient.'
But there is NO prohibition against blood transfusions in the Bible.
Same with polygamy. (except for in the case of elders.)
Eph 5:31
For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
1Ti 3:2
A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behavior, given to hospitality, apt to teach;
1Ti 3:12
Let the deacons be the husbands of one wife, ruling their children and their own houses well.
1Co 9:5
Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas?
1Co 9:5
Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas?
1 Cor 7:2 2
Nevertheless, because of sexual immorality, let each man have his own wife, and let each woman have her own husband.
1Co 9:5
Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas?
1 Cor 7:2 2
Nevertheless, because of sexual immorality, let each man have his own wife, and let each woman have her own husband
1 Cor 7:3 3
Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.
This was God's plan all along. He didn't create multiple Eve's. He created ONE Eve for Adam. Just because man has a habit of being disobedient doesn't justify disobedience. In EVERY situation where polygamy took place in the Bible, without God's blessing, nothing good has come from it. It seems clear to me that there is nothing good about polygamy. I believe we were to learn that from the Bible and not promote polygamy or pretend to be confused about it being wrong.
