The fight for joy is a fight to grasp and marvel at what happened in the death of Christ -- and what it reveals about our suffering Savior. If it were not for the death of Jesus in our place, the only possible joy would be the joy of delusion -- like the joy on the Titanic just before it hit the iceberg. Without the cross, joy could be sustained only by denying (consciously or subconsciously) the inevitability of divine judgment. In fact, that's the kind of joy that drives most of the world -- a joy that preserves the power of its pleasures by being oblivious to the peril just ahead. If the passengers were suddenly made aware that in a matter of hours most of them would drown in the icy ocean, all their merrymaking would cease. Their joy depends on their ignorance (John Piper, When I Don't Desire God, 71).
