In the creation of Adam, God delayed the giving of Eve as an object lesson to teach men how much they are to love, cherish, and be one with their wives. When wrongs are committed and the way forward is going to be rough, the only thing that will keep things together is love. Although sin causes separation in marriages, the reality is God blessed man with woman who was created by God for man to naturally, without thinking, cherish, love, and be one with. So when God said to love, cherish, and be one with your wife, He has already placed the programing in you to comply with this inspired statement.
Ephesians5:28 So ought men to love their wives as their own bodies. He that loveth his wife loveth himself. 5:29 For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church: 5:30 For we are members of his body, of his flesh, and of his bones.
5:31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
