"He told them another parable: 'The kingdom of heaven is like a mustard seed, which a man took and planted in his field."
In this parable, Jesus used a grain of mustard seed to accurately depict what His Kingdom (Christendom) would be like. It was contrary to what Israel waited for. The people were waiting for a political Messiah to powerfully come and overthrow their enemies and usher in a prosperous kingdom for all of Israel to take glory in.
However, Jesus presents a contradiction. The true Messiah had come to bring spiritual freedom. Christ came to redeem God’s people and restore them to a right relationship with the Father.
Likened to a mustard seed, Christianity seemed small and insignificant. Yet, in a matter of time, everything changed. The Good News of that first Christmas and first Easter Sunday spread. A tiny group of 12 disciples carried out The Great Commission. Seeds of faith were planted in the hearts of the enlightened.
The Church was built upon Christ, and she is continually growing. Indeed, the gates of hell have no power to stop the growth of God’s Kingdom.
