In preparation for Sunday's worship, think on these three things: (1) your motivation(s) for keeping God's commandments; (2) the difference between the works of the flesh and the fruit of the Spirit; and (3) how you express thankfulness for the blessings and healings God offers us in life.
In short, where do you stand in life - closer to the Samaritan leper who gave thanks, or the nine who "went their own way" and away from The Healer?
