And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof;
And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.
And Adam said, This [is] now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.
Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
Genesis 2:22-24
There seems to me to be a plan behind life perhaps even an author responsible for everything that is. It has always been since history has been recorded that no matter how cultures have struggled to shape an existence without accountability to God that here we are still living our lives as mandated in the Bible. In fact every society that has sought to liberate themselves from the bonds of Holiness to freely indulge the sins of the flesh has come to ruin.
Marriage is for God's children. I often wonder why folks who live in ignorance of God bother with marriage. It would seem that more folks are being true to their unbelief these days and just taking the same approach that the many species of animals around us take when it comes to relationship. Freedom from fidelity and total commitment to self preservation.
God is very explicit in His expectation that for His own there must be Love as Christ Loves the church. Everything God has set into motion must one day be brought back into perfect harmony with the creator. All stain of sin will be removed and the imperfect will be made perfect. The picture of woman from man returning to man to be one flesh is another exquisite example of what is to come when God's kingdom comes and His will is done on earth as it is in heaven.
What is more marriages truly and honestly reflected Jesus's love for the church.
