How grand is the view which this picture discloses, when in the interpretation of it we closely follow the Master's steps! It is, indeed, a parable concerning the kingdom of heaven. The whole world belongs to the King; he has placed his children in it, and commanded them to multiply till they people all its borders. The enemy has introduced among them evil persons, and within them evil thoughts. It is not a part of the omniscient Ruler's plan to remove, by the ministry of either angels or men, all the wicked at once from his world. For his own purposes, which are only in part discernible by us, he permits the good and the evil to mingle and contend with each other until the fulness of time, as he left the Canaanites in the land to chastise and exercise his chosen people. When the tares prosper, the wheat languishes: when the wheat prospers, the tares languish. Evil men have lived in God's world ever since sin began: evil thoughts and deeds will be found in God's children as long as they remain in the body. The angels are not sent to-day to make such a separation as would leave the children of the kingdom nothing to do, or to bear. If you desire the heavenly to prosper within you and around you, fight with the proper weapons against the devilish: if you desire the devilish within and around you to languish and decay, cherish the heavenly. As David's house waxes stronger, Saul's house will wax weaker. When Christ gets more of the world and of our hearts, the devil will get less. THE MUSTARD-SEED, AND THE LEAVEN.
