This sermon explored how joy — our most precious possession after salvation — is constantly under threat of being stolen by our circumstances, anxiety, and the enemy. Drawing from Philippians 4, we discovered that joy is not the absence of trouble but the presence of Christ. Paul's command to "rejoice in the Lord always" isn't just wishful thinking; it's a supernatural response made possible through prayer, gratitude, and contentment in Christ. The message challenged us to recognize that losing our joy is often an "inside job" — we allow it to be stolen by failing to apply God's Word and maintain proper internal spiritual stabilizers in our lives.
