In this sermon from Psalm 137 and titled, "Have You Lost Your Song?" Pastor Byron explores the profound despair of the Israelites in Babylonian captivity, illustrating how they lost their ability to sing and rejoice. The sermon delves into the reasons behind their silenced songs; captivity, mockery from their captors, and a profound sense of loss. Pastor Chesney connects these themes to modern struggles where Christians may feel their joy and praise stifled by life's trials. He emphasizes that despite hardships, our spiritual song can be restored through repentance and a renewed connection with God.
