The apostle then applied the principle of mutual submission to many different relationships, the first of which was marriage. When a man and woman take their wedding vows, they enter a love relationship that calls for a lifetime of submission to one another. Submission and love go together. In a Christian marriage, husband and wife, because they love God, are submitted to what the will of God is for them. They are in a process of letting go of themselves and submitting to God and to each other.
Marriage is a struggle of wills.
Marriage is overcoming self. Marriage is being a servant. Marriage is giving up and giving in. Marriage is doing dishes when she's too tired. Marriage is laundering his favorite shirts.
