I can't say this any better than the footnotes in my Bible, so know the following is from there and not my own words. The Life Application Bible: NIV commentary says that marriage was instituted by God and has three basic concepts (1) the man leaves his parents and in a public act promises himself to his wife, (2) the man and woman are joined together by taking responsibility for each other and by loving their mate above all others (3) the two become one flesh in the intimacy and commitment of sexual union that is reserved for marriage.
These are important concepts. Number two mentions loving your mate above all others. . . this includes the children. This is an issue in many marriages where the wife (or husband) is so busy with the children that they have little left for their spouse. Knowing how God intended "the pecking order" to be BEFORE I was married enabled me to keep that focus once children arrived. My children will leave our home eventually, my marriage is for life. If I don't take care of this relationship through the years (while the kids are in the home) then it won't be strong and healthy once the kids leave. Some might disagree and that is there right, but I am taking my imformation straight from the source of TRUTH- the Bible. Who can argue with God?
