Have you ever been so overjoyed that you shouted out loud? Have you ever been so overwhelmed with someone that you fell down in front of them? We see both of these responses in the life of one leper healed by Jesus. But what happened to the other nine? As we see in Luke 17:11–19, it is possible to be glad for Jesus' gifts without being grateful to Jesus and for Jesus himself. Thanksgiving sounds easy enough. We're taught to write thank you notes as children. But true thanksgiving in the heart is a miracle God works in those who are his children by faith.
