I and my husband are christian and we knew each other in church. I think the same belief to us is very important because I have found the common ground between us. Since we can share the same values, there is not much conflict or pressure in our relationship. I thanks God let me have a husband who is already a christian, so I no need to pray for him to become a christain one day but I have to pray for our spirit. If our spirit is not good, I can't find the difference between christian and non-christian
Anyway, if my husban is not a christian, I think I have to overcome more problems. Even without any belief conflict, having good relation with another half is not easy.
Hope you can believe God as earlier as possible and HE will lead you to wallk a right way in your life.
