Here's the bottom line: Our culture makes us consumers, but consumers don't make good disciples.  Jesus calls us to surrender, to submit, to live every moment for his glory and purpose, knowing that our hope is not in today but in eternity.  Then your life will find the fulfillment no sunrise over the ocean can ever supply.

Dietrich Bonhoeffer, the German theologian who gave his life to fight Nazism and stand for the gospel, was right: "when Christ calls a man he bids him come and die."  That's because only a person who dies can be resurrected.  Only what we give to God can be blessed by God.  Only what we submit to his perfect will can experience his perfect will.  Only those who walk with Jesus can know the joy of Jesus.

So trade up.  As Lewis reminds us, aim for heaven and you'll get earth thrown in; aim for earth and you'll get neither.  Trade in your Elantra for a race car, your sunrise over the ocean for a sunrise one day in Paradise.  You'll be glad you did, now and forever. 

This is the invitation of God.
