The engagement of the heart in worship is the coming alive of the feelings and emotions and affections of the heart. Where feelings for God are dead, worship is dead.
John PiperThe assurance of the believer is not that God will save him even if he stops believing, but that God will keep him believing--God will sustain you in faith, he will make your hope firm and stable to the end. He will cause you to persevere.
John PiperOnly the # gospel can do two seemingly contradictory things: destroy pride and increase courage.
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 PiperMarriage 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.
