A lot of Christians are cast down, losing their peace and joy because they don’t expect attacks on their peace and joy. We’re sad that we’re sad. We’re upset that we’re upset. We say, “it’s not supposed to be like this!” because we don’t have the proper expectations.  Before you became a Christian, your main enemy in life was God: someone who loved you, who was doing everything he could to wake you up. But the minute you make peace with God, instantly, all of God’s enemies declare war on you—and they’re not nice enemies.  We’re going to look at 1) what the Bible says about peace and joy, 2) our three enemies, and 3) the attacks on assurance.  This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on February 18, 1990. Series: Fruit of the Spirit. Scripture: Philippians 4:4-9.
