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.
John PiperJesus' teaching in general [implies] that happy and fulfilling sexual relations in marriage depend on each partner aiming to give satisfaction to the other. If it is the joy of each to make the other happy, a hundred problems will be solved before they happen.
John PiperWe embrace the hand we've been dealt, because we know the Dealer, and he never deals badly.
