I assume, since I have not read many materials on what a Christian should do if they win the lottery, it means either many Christians are ashamed to admit that they play the lottery and/or many Christians believe that playing the lottery is a sin. Is it though?
Marriage is oneness. Without it, a marriage really isn’t a marriage. It is cohabitation. Cohabitation isn’t what you ‘signed on’ for the day you said “I do”. Marriage is what you had in mind, so don’t settle for anything less.
