The sermon reflects on the story of the ten lepers in Luke 17, emphasizing that while all were physically healed, only one returned to Jesus in gratitude—and that this thankful response revealed a deeper, saving faith. Pastor McKinley uses the passage to illustrate humanity’s desperate need for mercy, Christ’s decisive work of grace, and the transformative power of returning to Him with a grateful heart. He concludes by urging believers to cultivate daily gratitude—especially in hardship—as the proper response to God’s continual mercy, grace, and salvation.
