Mustard Seed of Faith

Last week's Gospel was Luke 17:5-10, which includes the mustard seed amount of faith,"If you had the faith like a mustard seed, you would say to this mulberry tree, 'Be uprooted and be planted in the sea'; and it would obey you" Luke 17:5 (NASB). 

In the Bible Study on this lesson we tended to remark on our lack of faith.

Maybe it is more to the point that even a small amount of faith can accomplish great things.  In the children's sermon, the story of "the little engine who could" was used, demonstrating what you have faith that you can do, you can do.  What great things can Trinity United Lutheran Church accomplish?
