The Parable of the Mustard Seed and the Leaven
These two cannot be separated: one might say that it is because of the invisible principle of eternal life, by the Holy Spirit planted in the hearts of the citizens of the kingdom and increasingly exerting its influence there, that this kingdom also expands visibly and outwardly, conquering territory upon territory.
Even today mustard grows vigorously in Palestine. It reaches ten feet, sometimes fifteen. In the fall of the year, when its branches have become rigid, birds of many kinds find here a shelter from the storm, rest from weariness, and shade from the heat of the sun, all in all a wonderful place to go tenting! “The kingdom of heaven in its outward manifestation on earth is like that,” says Jesus. It is seemingly insignificant in its beginning, but from this small beginning great results will grow.
Relatively speaking, the group of Christ’s loyal followers was so small and so weak that at times they must have almost despaired.
They were looking for revolutionary changes right here and now (Matt. 21:8, 9 and parallels; Luke 9:54; John 6:15; Acts 1:6). They may have asked, “Did not John the Baptist point in this direction?” See Matt. 3:11, 12. “Did not the Old Testament contain prophecies concerning the exaltation of Israel, its expansion among the nations, and its cosmic significance during the Messianic age?” See Gen. 22:17, 18; Ps. 72:8–11; Isa. 54:2, 3; chap. 60–62; Jer. 31:31–40; 32:36–44; Amos 9:11–15; Mic. 2:12, 13; 4:1–8; chap. 5; Zech. chap. 2; 8:18–23; etc. But in the thinking of the people these passages if pondered at all were probably often lifted out of their contexts.
