The message of Desiring God is that God is most glorified in us when we
are  most satisfied in him. In this book, Piper calls this worldview
“Christian Hedonism” and explains why pursuing maximum joy is essential
to glorifying God. He discusses the implications of this for
conversion, worship, love, Scripture, prayer, money, marriage,
missions, and suffering.

One way to see the glory of God is to meditate upon the object of his
delight. In this reissued version with a new cover design, John Piper
unfo  lds for us a vision of God through the lens of his happiness. What
most delights the happiest Being in the universe? God’s gladness in
being God. If God’s excellencies can be admired in his pleasures, and
if we tend to become like what we admire and enjoy, then focusing on
these pleasures can help us to be gradually conformed to his likeness.
In other words, we will be most satisfied in God when we know why God
is most satisfied in God. This version includes the same content as the
revised and expanded edition published in 2000.

What is future grace? It is all that God promises to be for us from
this second on. Saving faith means being confident and satisfied in
this ever- arriving future grace. This is why saving faith is also
sanctifying faith. The power of sin’s promise is broken by the power of
a superior satisfaction; namely, faith in future grace. Gratitude for
past grace was never meant to empower future obedience. Tomorrow’s
crisis demands tomorrow’s grace. And faith that future grace will be
there is the victory that overcomes the world. Future Grace contains 31
chapters – one for each day of the month – including practical chapters
on how faith in future grace defeats anxiety, pride, shame, lust,
despondency and more.
