This document discusses how Christians can restore the joy of their salvation. It begins by examining passages from Psalms and Philippians about rejoicing. It then asks whether readers have truly experienced salvation or if their joy was based on other things that could be lost. The document suggests examining one's life for unresolved sin or anger at God as potential reasons for lost joy. It encourages rejoicing in God's character, works, and salvation both privately and corporately in all circumstances, according to the example of Habakkuk. The overarching message is that Christians should rejoice in the Lord always.
