He ran back to Jesus

One of them, when he saw he was healed, came back, praising God in a loud voice. (Luke 17:15 NIV)

 The Gospel of Luke tells us that as Jesus was making His way to Jerusalem, ten men who had leprosy approached Him and called out from a distance, “Jesus, Master, have mercy on us!”. Jesus was moved with compassion and told them to go show themselves to the priests. (Luke 17:11-19)
 It’s interesting to wonder what might have gone through their minds as they left Jesus. We can imagine how thrilled they all must have been when they realized that the miracle had taken place, but Luke tells us that only one of the men was so filled with gratitude that he ran back to Jesus, praised God in a loud voice, and threw himself at Jesus’ feet to thank Him. He was a Samaritan
 “Didn’t I heal ten men?” Jesus asked. “Where are the other nine? Has no one returned to give glory to God except this foreigner?”
 The lepers all showed faith that Jesus would heal them, as they set out to find a priest while they were still sick, but Jesus’ comment highlighted their lack of gratefulness. From this account, we see that God doesn’t just want His followers to believe in Him, He also should be recognized and praised in every situation. “Be thankful in all circumstances, for this is God’s will for you who belong to Christ Jesus.” —Ronan Keane [1]

 Gratitude is an offering precious in the sight of God, and it is one that the poorest of us can make and be not poorer but richer for having made it. —A.W. Tozer
