Well, in the last 33 years I have read the Bible perhaps a 100 times or more, studied it diligently, read entire sets of biblcal commentaries (OT & NT), have a BA in Biblical Studies, an MA in Christian Counseling, and have spent years on my face before God seeking after His will, purpose, and plan. You may also wish to entertain some thoughts on Paul’s advice to Timothy & Titus regarding qualifications for the man of God being that of the “husband of ONE WIFE,” (1 Timothy 3:2; Titus 1:6). Combined with the “whole counsel of God,” this qualification would apply to all who “name the name of Christ.” God’s plan for man was one husband, and one wife.
I never suggested you haven’t studied the Bible, nor have I called into question your sincerity in seeking God, but I have studied this topic in great detail, including the scriptures you have referenced. I also said you might prove me wrong, but saying you have spent great time in the Word and seeking God’s will doesn’t mean you have studied a topic in great depth. I would challenge you to do so with this topic and then see if your response is the same.
Regarding the scriptures you shared, there is some uncertainty on “one wife” because of the word mia, which can also mean “a wife” which would in contrast suggest marriage was a requirement, but not marriage to only one.
