In Luke 17 Jesus encounters 10 men who have a terrible disease. They cry out to Jesus asking for help. Jesus simply tells them to go to the priests, which is the social and religious protocol for those with this disease. On the way, they are healed. But only one returns to Jesus and personally, as well as publically, gives him thanks. And in Isaiah 12 the prophets looks inot the future and sees a time when God's people will constantly praise and thnk him.
