1. It is like a mustard seed (18,19)
The kingdom of God is like a tiny mustard seed that is planted in a garden. The seed grows into a large tree that changes and blesses the environment. If there is one person in a school or business or nation who has been changed by Jesus and who has God ruling in his heart, the kingdom of God will grow and spread until it makes the world a better place. One person who loves God can change a nation. This is how God works. When God's word is planted in our hearts, it grows until we are changed into people whose lives and influence are a blessing to others.
2. It is like yeast (20,21)
The amount of yeast used in making bread is insignificant, but its influence on the whole lump of dough is great. For without the yeast, the bread won't rise. When God's word is planted in our hearts, it works quietly until our whole lives are changed. God's kingdom is invisible, but its influence in the world is essential to the life of the world. May God's kingdom come on earth as it is in heaven.
Application: Lord, give me faith to trust your slow, steady and invisible way of working.
One Word: God's kingdom is small and growing
