On the weekend before I had surgery for thyroid cancer, I wrestled with this question: “How do you face troubles with peace?” I came to realize it’s not petitionary prayer that helps you face troubles.  Of course the Bible is filled with petition, where you go to God and make your needs known. And you should do that. But the ultimate and main way to handle the troubles of life is not just through petitionary prayer, but through worship.  Psalm 95 is the classic text about worship. It tells us almost everything we need to know: 1) what is worship? 2) why should we worship? and 3) how can we worship? This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on July 7, 2002. Series: Psalms: Disciples of Grace. Scripture: Psalm 95:1-11.
