What is the difference between being grateful and thankful?

Thankfulness is the fruit of gratefulness. No one owes us anything! If we buy the lie people or God owes us something, we plant and nurture the seed of our own destruction. Luke 17:15-19”One of them, when he saw he was healed, came back, praising God in a loud voice. He threw himself at Jesus’ feet and thanked him—and he was a Samaritan. Jesus asked, Were not all ten cleansed? Where are the other nine? Has no one returned to give praise to God except this foreigner? Then he said to him, Rise and go; your faith has made you well. “Ephesians 5:20-21,”Always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ. Submit to one another out of reverence for Christ.”
