Mark 4:32
But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it. But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it.
The mustard seed is among the smallest seeds yet grows into a large vigorous plant that rises above grass and grain and puts out great branches where birds rest and lodge in its shadow. It shows Christ's kingdom beginning in a humble obscure way with only a few Galilean peasants who seemed powerless beside earthly kingdoms, then growing and spreading through the world into a great mighty sheltering power while those kingdoms perish. That growth is gradual and through stages, coming from the divine life God placed within it and not from human power, armed force, or outward display. The same pattern is repeated in every generation as the truth for that time advances through humble believers, and it reaches its triumph when the final message of warning and mercy is proclaimed to every nation to gather a people and lighten the earth with glory. It also pictures grace working in the heart, where a spoken word or ray of light quietly starts a new life that endures opposition and grows in strength and fruitfulness, and where Christ's own brief simple utterances carry the vital energy of His Spirit to awaken need in a way elaborate argument seldom does.
Seed's Smallness and Greatness
The mustard begins as one of the smallest seeds yet develops into a large, vigorous plant. When seen growing it rises above the grass and grain around it. It puts forth great branches in which birds rest and sing and under whose shadow they find lodging.
Its increase is gradual and through stages, driven by the divine life and life principle placed within it. That power makes what starts humble and seemingly insignificant become great, strong, and far-reaching. The growth does not come from human power, force of arms, armed force, military display, or the pomp of war, but from the strength of its own life and the quiet, strengthening work of divine grace.
Kingdom Grows From Smallness
Mark 4:32 shows the kingdom of Christ beginning in a humble, obscure, and seemingly insignificant way, represented at first by only a few Galilean peasants. Its work starts with few advocates who may be opposed and despised and who seem obscure and powerless beside earthly kingdoms. From that beginning it grows and spreads throughout the world into a great, strong, mighty and far-reaching sheltering power. The earthly kingdoms that once seemed powerful perish, while its influence outlasts them and remains.
That growth is repeated in every generation as God's truth and work advance through a special truth and work for each time. That special work is often received by humble people rather than the worldly-wise or the established religious authorities. Its few first advocates face battles and win victories, as seen in John the Baptist, Paul and Silas, Luther, and Wesley.
Its triumphant fulfillment in the last generation is the worldwide proclamation of the final message of warning and mercy. That message will go to every nation, gathering a people for God. It will lighten the earth with His glory.
Seed in Heart and Ministry
The verse pictures divine grace and the life-giving word at work in people, not only a kingdom growing in the world. A spoken word, a ray of light, or a quiet influence can start new life in the heart, and the results of that beginning cannot be measured. Christian experience and faith may begin in a small and apparently insignificant way, yet endure even when trampled upon or opposed. That small beginning grows in strength and beauty and fruitfulness through the quiet, strengthening, quickening power of the word.
Christ likened His own utterances of divine truth to the mustard seed. Simple, brief statements spoken from a heart made soft and sympathetic by love work as that seed works. He throws into the soul the vital energy of His Spirit to make the seed of truth germinate and bear fruit. In this way He impresses the hearer with a sense of need and peril, which elaborate reasoning or argumentative demonstrations of doctrine seldom do.
The truth must be sown and cultivated in prepared soil. The heart must be cleared of sin and selfishness and warmed by the light of the Sun of Righteousness. God's unseen power supplies what is needed for growth and harvest. The gospel is a mystery beyond human wisdom, revealed by the Spirit, and its truth is to be woven into practical life.
The truth gathers up one here and another there, and from every truly converted soul the work enlarges and spreads further. Ministerial labor must therefore not be kept in a narrow compass but must go out in different directions planting the standard of truth so the light shines forth to others. Beginning in Massachusetts and Maine the work spread into different states. Workers who trusted fully in God's power to help received help at the very time they most needed it.
