From The Hidden Smile of God by John Piper:

The fruit of William Cowper’s affliction is a call to free ourselves from trite and chipper worship. If the Christian life has become the path of ease and fun in the modern West, then corporate worship is the place of increasing entertainment. The problem is not a battle between contemporary worship music and hymns; the problem is that there aren’t enough martyrs during the week. If no solders are perishing, what you want on a Sunday is Bob Hope and some pretty girls, not the army chaplain and a surgeon.
   Cowper was sick. But in his sickness he saw things that we so desperately need to see. He saw hell. And sometimes he saw heaven. He knew terror. And sometimes he know ecstasy. When I stand to welcome the people to worship on Sunday morning, I know that there are William Cowpers in the congregation. There are spouses who can barely talk. There are sullen teenagers living double lives at home and school. There are widows who still feel the amputation of a fifty-year partner,. There are single people who have not been hugged for twenty years. There are men in the prime of their lives with cancer. There are moms who have risked all for Jesus and bear the scars. There are tired and discouraged and lonely struggles. Shall we come to them with a joke?
   They can read the comics every day. What they need from me is not more bouncy, frisky smiles and stories. What they need is a kind of a joyful earnestness that makes the broken heart feel hopeful and helps the ones who are drunk with trifles sober up for greater joys.

—John Piper, The Hidden Smile of God, 167.

I have recently finished reading a series of books by John Piper called The Swans Are not Silent. You may have read the several excerpts I have posted as I read. In my mind, nothing short of Scripture serves to inspire and encourage like the biographies of great saints of the past. This series has been especially good that way.

These books are a great entry-point into the history and theology of the Christian church. Rich in theology and fascinating in history, yet written on a level that should be easily understood by anyone of high school age and up, they will whet your appetite for more—more history, more theology, more of God’s working through the ages.

Titles in the series are:
• The Legacy of Sovereign Joy: God's Triumphant Grace in the Lives of Augustine, Luther, and Calvin
• The Hidden Smile of God: The Fruit of Affliction in the Lives of John Bunyan, William Cowper, and David Brainerd
• The Roots of Endurance: Invincible Perseverance in the Lives of John Newton, Charles Simeon, and William Wilberforce
• Contending for Our All: Defending Truth and Treasuring Christ in the Lives of Athanasius, John Owen, and J. Gresham Machen

The thumb-nail sketches of great theologians of the church from Augustine and Athanasius to J. Gresham Machen show us that the struggles we face are not greater than those that Christians have faced since the beginning of the church; that the heresies that are prevalent today are the same attacks on the truth that Satan has been using for centuries; that the truth that has sustained God’s people is the same truth that sustains us today; and that the one true God upon whose grace we rest is as faithful today as he has always been—“Jesus Christ the same yesterday, and to day, and for ever.”
