It is foreign to us to give praise and thanks to the source of our blessings (Luke 17:11-19, especially v 18). Complaining is more native to our tongues (Numbers 11:1-14). "The devastation of sin is most evident in the difficulty that we have with prayer." (Weedon's New Lutheran Quote of the Day for yesterday, from John Kleinig, *Grace Upon Grace* p. 156)
Lord, we are truly unworthy servants. We have not done our duty. Increase our faith indeed! (Luke 17:5, 10).
