As Christians we have set a horrible example for the world. We have shown everything but Christ and the church. Wives have rejected the headship of their husbands. Husbands have not loved their wives sacrificially. Marriages fail with alarming frequency.
Marriage counselors do booming business.
So do divorce lawyers. We need to look in the mirror of our own marriages. This is what erodes the foundations of a marriage. Husbands and wives need regularly to confess these things to one another, and forgive one another, as God has forgiven them in Christ. We need to be cleansed by the water and the Word.
