Yes. Haha, christians do divorce due to unreconciable differences. I can say that church belongs to an east malaysian denomination.
I know both of them, they both quite pious one. Sometimes i think the christian girl is too careful and stringent until she forget about the romance of the relationship.
Also its the guy's fault because he tries to be too accomodating. Then after the relationship, when get married, only then he bother to stand firm against her (too late). So in conclusion, all that carefulness go down the drain. Why? Because i see my non-christian friend marriages can last more happier and longer.
I got one non believer friend, his marriage was on the rockers because his wife got attitude problem, so he confronted her and argued with her. I also know she has very bad attitude problem, never change even when my unbeliever friend was boyfriend-girlfriend to her. Then when something big happen during their marriage, my friend was about to consider divorce, to my shock, the wife changed for the better ! When I met his wife recently, she completely changed, she became kinder and more nicer person. My friend decided to stay in the marriage.
But unfortunately some christians are so dogmatic. These are problems they face, they think they got the authority from God to be "right all the time". They cannot be corrected, they think they are unfallable.
So in a christian marriage, the guy got big big ego, he will quote biblical verses during argument with the wife, and she also quote back. They both think they got the dogmatic rights to win the argument. So end up divorce.
I have encountered a lot of big ego christian guys. When I try to suggest something, they just shut me out because they think they been given god given powers to override. I also brought up some issues about how we can improve the church stuff, then it wasn't a big deal, one of the christian leaders, got offended and walked out on me. I check with my other friends about what i said, and they say it wasn't offensive nor questioning authority, just that he overreacted.
Its just so unfortunate, when guys go to church thinking that they got the God given right to steam roll over other people but they forgot that Jesus came down to Earth with kindness and compassion to love. Sometimes when i got to church and when I see lack of love, i just don't think the place is suitable for me. Sometimes I got out yam cha with my non christian friend, he tells me about his suffering, and i feel compassion to help and emphathize with him because I love Jesus then I also must love the people who are in suffering because thesse are the people Jesus love.
I have been to church when a troubled christian guy keep on saying that he wants to commit suicide. He makes statement like tommorow i want to jump down 13th floor. He looks very troubled. He tells these things in our gatherings but the dogmatic leaders listen and just ignore him. Where is the compassion?
So it all starts from the heart. We can be very careful and stringent with our partners but if we don't have a loving and compassion heart like Jesus, we are no where near prepared for a marriage.
This is called spiritual pride. They are proud because of their so called spirituality. We can fall into this too sometimes when not aware especially those who do more for the church and the leaders in the church.
Anyway, back to your friends. they should work on their marriage no matter how challenging and not to divorce. God's will for marriage is life-time commitment. And their divorce is not 'valid' also in God's eyes. There are only 2 valid divorce in the church. One is when the spouse pass away. Secondly is due to marital unfaithfulness. I find the verse for this next time ya.
