The Mustard Seed – Luke 13:18-21
Jesus compared the Kingdom of God to a mustard seed tree. It is the smallest of seeds but grows into a large plant or tree. Jesus said that faith is like that. It starts out small but when allowed to mature it becomes a great factor in spiritual life. Jesus also address here about yeast. Yeast in bread grows and works through the bread. Both good and bad things happen when these things are present. When faith is present the glory of God is exhibited. When the yeast of the Pharisees is allowed to make it way through the heart it can spoil or destroy the things God wants to do in our hearts.
