In this account of Jesus healing the ten lepers, Jesus is teaching the truth that all good for this life and beyond comes from God through faith in him. We can trace all the blessings in our lives back to him. Yet it is in our sinful nature to complain and forget our blessings. Thankfulness is a learned behavior. By stopping to think about where good things come from, we can live lives of thankfulness to the God who gives us all, including forgiveness and eternal life.
