The greatest stumbling block for children in worship is that their parents do not cherish the hour. Children can feel the difference between duty and delight. Therefore, the first and most important job of a parent is to fall in love with the worship of God. You can't impart what you don't possess.
John PiperHe has made me wary of chronological snobbery. That is, he showed me that newness is no virtue and oldness is no vice. Truth and beauty and goodness are not determined by when they exist. Nothing is inferior for being old, and nothing is valuable for being modern. This has freed me from the tyranny of novelty and opened for me the wisdom of the ages.
John PiperThe ultimate difference between God's wisdom and man's wisdom is how they relate to the glory of God's grace in Christ crucified. God's wisdom makes the glory of God's grace our supreme treasure. But man's wisdom delights in seeing himself as resourceful, self-sufficient, self determining, and not utterly dependent on God's free grace.
John PiperOur deeds are not the basis of our salvation, they are the evidence of our salvation. They are not foundation, they are demonstration.
John PiperExultation that does not flow from education, affections that do not flow from knowing, savoring that does not flow from seeing, feeling that does not flow from thinking - are hollow and rootless - noisy gongs and clanging cymbals. And God is not glorified by artificial and empty passions. True delight is rooted in true doctrine. God-centered exultation is rooted in God-centered education.
