Almost two years ago now, my brother's wife left him for another man. The day she moved out was one of the saddest days of my life. I sat with my brother at their home and watched her pull up with the moving truck and one of her best girlfriend's and watched her load the truck up and leave. I watched my brother just look at her and hold back the tears. At one point, I couldnt take it anymore and I had to run out of the house. I didnt want my brother to see me cry because I was there to support him, but I was losing my sister and I just couldnt believe that she could let adultery seep into their home and ruin their marriage. While they were in the process of divorce, I invited my brother to church with me and spoke to him about the Lord and my brother got saved by himself reading his bible at home. He knew that divorce was not for the Christian, so He wrote her love letters and tried calling her (she turned off her phone when he would call though).. When he did talk to her he asked if she would see a Christian counselor with him and she refused, saying that a Christian counselor would want them to work at a marriage that wasnt worth saving to her.. It was horrible. Well, two years later, and my brother just got married to another lady.. a fantastic Christian lady who's husband left her right at the same time that my brothers wife left him (he however, was a gay man.. he left her for his perversion). I love her, but.. but, sometimes I am still so angry because she is NOT who he is supposed to be with. I know there is nothing that can be done now. I know that they are divorced and its over and everything is fine on the surface.. However, I was reading the question concerning divorce in a different post, and I guess my question is this.. If my brother and his first wife are eternally married in God's eyes.. does this mean that his marriage to his new wife is invalid? and if so, does this mean that if his old wife came back after repenting, that he would have to leave his wife now and go back to her? biblically speaking, is his marriage now nothing but continual adultery? this is where it gets foggy for me.
