Quotes from John Piper

The wonder of marriage is woven into the wonder of the gospel of the cross of Christ, and the message of the cross is foolishness to the natural man, and so the meaning of marriage is foolishness to the natural man.

Husbands and wives, recognize that in marriage you have become one flesh. If you live for your private pleasure at the expense of your spouse, you are living against yourself and destroying your joy. But if you devote yourself with all your heart to the holy joy of your spouse, you will also be living for your joy and making a marriage after the image of Christ and His church.
