The tiny mustard seed literally grew to be a tree which attracted numerous birds because they loved the little black mustard seed it produced. God's kingdom works in a similar fashion. It starts from the smallest beginnings in the hearts of men and women who are receptive to God's word. And it works unseen and causes a transformation from within. Leaven is another powerful agent of change. A lump of dough left to itself remains just what it is, a lump of dough. But when the leaven is added to it a transformation takes place which produces rich and wholesome bread when heated – the staple of life for humans. The kingdom of God produces a transformation in those who receive the new life which Jesus Christ offers. When we yield to Jesus Christ, our lives are transformed by the power of the Holy Spirit who dwells in us. Paul the Apostle says, "we have this treasure in earthen vessels, to show that the transcendent power belongs to God and not to us" (2 Corinthians 4:7).
