Jesus compared the Kingdom of God to a mustard seed as well as the leaven in the dough. The Kingdom is first and foremost a spiritual one. The Lord did not come to overthrow the government of His time and establish an earthly empire. Jesus came into the world to save His people from their sins. This Kingdom begins small, like a mustard seed and begins to grow in reach and power. One day His kingdom will permeate the entire world and He will come in victory to establish His eternal rule. The seed of the kingdom falls upon the hearts of men in the good news of the gospel. What kind of soil is your heart to receive it?
