Luke 17:17-19 (KJV) And Jesus answering said, Were there not ten cleansed? but where are the nine? There are not found that returned to give glory to God, save this stranger. And he said unto him, Arise, go thy way: thy faith hath made thee whole.
Giving thanks began in the four Gospels with Jesus. Up until Jesus no one gave thanks for their bread. Jesus never missed an opportunity to thank His Father. Jesus is our model. WWJD? We know what He did! It's in the Word. Read it! Do it!
