In this Sunday's reading from Luke 17:11-19, Jesus heals ten lepers,

On the way to Jerusalem Jesus was going through the region between Samaria and Galilee. As he entered a village, ten lepers approached him. Keeping their distance, they called out, saying, ‘Jesus, Master, have mercy on us!’ When he saw them, he said to them, ‘Go and show yourselves to the priests.’ And as they went, they were made clean. Then one of them, when he saw that he was healed, turned back, praising God with a loud voice. He prostrated himself at Jesus’ feet and thanked him. And he was a Samaritan. Then Jesus asked, ‘Were not ten made clean? But the other nine, where are they? Was none of them found to return and give praise to God except this foreigner?’ Then he said to him, ‘Get up and go on your way; your faith has made you well.’

Only the Samaritan came back to thank Jesus. 

Do we remember to thank him and praise him when things go our way?

I have known some remarkable Christians who thank him and praise him as they suffered from cancer.

We have no excuse when we forget to do so during the good times.
