Marriage is not mainly about prospering economically; it is mainly about displaying the covenant-keepin g love between Christ and his church. Knowing Christ is more important than making a living. Treasuring Christ is more important than bearing children. Being united to Christ by faith is a greater source of marital success than perfect sex and double-income prosperity.
John PiperTo love God does not mean to meet His needs, but rather to delight in Him and to be captivated by His glorious power and grace, and to value Him above all other things on earth. All the rest of the commandments are the kinds of things that we will do from our hearts, if our hearts are truly delighted with and resting in the glory of God's grace.
John Piper
