That is definitely the truth. Now, I married my husband before I was saved. He still has not been saved. I try without trying to be all preachy with him to explain the Truth. He argues science with me. Even before I was saved I was never one to believe in divorce, and I still love my husband anyway. That won't go away. I continue to pray and hope that salvation will come to him one day, but I do get discouraged sometimes.
Don't be discouraged...as you continually live for Christ you are a living testimony to God's mercy, grace, and unconditional love. You just keep living as the child of GOd that you are, an inevitable positive example to your husband, and watch God show up and show out so He can get all the glory. Salvation will be your husband's, all he has to do is receive it.
I doubt that would revoke your salvation... but the bible does say that we should not be unequally yolked.
This is nothing but God having me to read and reply to this now, because I've been spending time with a co-worker, outside of work, and we seemed to really hit it off. Lots of chemistry, and just really having a good time, but He's not saved. A very good guy, definitely husband material, but NOT SAVED... So I'm ministering to myself as well. It won't be a peaceful situation with Satan and Christ living in the same house.
