The Gospel of Luke radically changes many popular ideas about faith. Bible teachings about mustard seed faith usually focus on how even tiny faith can do amazing things. But the five Scriptures about mustard seeds show another feature that completely changes the analogy. Every Scripture that mentions the tiny size of the mustard seed also shows the wondrous growth into a large plant that provides for others. Mustard seed faith is faith that wll grow. When the apostles asked Jesus to increase their faith in Luke 17, His analogy of faith to a mustard seed shows that faith will grow well if it is sown and cultivated. In Luke the apostles had mustard seed faith. In Acts they had mustard tree faith. This book shows Luke's description of God's work to transform their faith. Faithful believers in Jesus can see how God is working to transform their own faith into being a source of great blessings, and can see how to work with Him for this blessing.
