"The righteous will shine like the sun in the kingdom of their Father"

Scripture: Matthew 13:24-43
The image Jesus uses here is a common everyday example of planting, harvesting, and sorting the good fruit from the bad. Weeds can spoil and even kill a good harvest if they are not separated and destroyed at the proper time. Uprooting them too early, though, can destroy the good plants in the process. Just as nature teaches us patience, so God's patience also teaches us to guard the word he has planted in our hearts and to beware of the destructive force of sin and evil which can destroy it. God's word brings life, but Satan seeks to destroy the good seed which has been planted in the hearts of those who have heard God's word. God's judgment is not hasty, but it does come. And in the end, God will reward each according to what they have sown and reaped in this life. In that day God will separate the evil from the good.
What can mustard seeds and leaven teach us about the kingdom of God? 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.
