Hello ServantforChrist
God bless you this day, and welcome to Christianity Oasis.
Your question is an intriguing one -- it made me stop and think.
One would hope that the first marriage was in the Lord and in truth, but, we both know that that is not always the case, therefore, if it wasn't in the Lord and in truth, then it would not have been a real marriage, soooooooo, at that point a first real marriage in the Lord and in truth had not yet taken place. If that be the case, then, any upcoming marriage would be the first (if in the Lord and in truth), and not a remarriage.
However, that may just be a study in semantics -- or maybe not???
In the 4th chapter of the Book of John, the Samaritan woman at the well: we read that she had had 5 husbands. Yet, Jesus stated that she has no husband (verses 17 and 18). The Bible doesn't mention anything about whether the previous 5 husbands died or not...it merely says that she has no husband. Jesus also mentions that the man she was currently with, was not her husband -- I take that to mean that she never bothered going through a marriage ceremony with that one, but was living with him. But, I could be wrong.
What I do know is that Jesus loved her, and He knew everything about her, and their time together was precious to both of them, and she was forever changed. Hallelujah!!! Thank You Jesus!!!
Our spiritual union with Christ Jesus allows us to know His will for our life. Jesus is the way, the truth and the life.
Thank you for your question. I look forward to hearing your understanding on this topic. I hope others will share what their heart-felt understanding is, as well.
God bless and keep you, ServantforChrist.
In Christ Jesus' love,
