David had disappointments galore as he fled from Absalom. Most people would have focused on those crushing disappointments and been overwhelmed with sadness, but David mysteriously experienced joy and a "river" of God's pleasures while aggressively taking his disappointments to the God who cares. This sermon shows how we too can "rejoice in the Lord always" (even in the midst of numerous disappointments) without adopting an unrealistic Pollyanna Christianity.
