I am kind of at a loss for words on this subject because my answer is simple.
Just as believing Him, praising Him, loving Him and patterning my life after Jesus Christ makes me a Christian, in order for a couple to have a marriage that is "Christian" we should be reflecting Jesus Christ ---- together.
Maybe I don't get the question, but that is my contribution to Marriage Monday.
I know I will learn a lot by all those that will be participating. Visit our hostess blog for her write and links to others participating on this Marriage Monday topic. You will be blessed! You can join the group by checking out e-Mom's blog if you would like to share too.
