26And He was saying, "The kingdom of God is like a man who casts seed upon the soil; 27and he goes to bed at night and gets up by day, and the seed sprouts and grows—how, he himself does not know. 28The soil produces crops by itself; first the blade, then the head, then the mature grain in the head. 29But when the crop permits, he immediately puts in the sickle, because the harvest has come."
Mar_4:26 "seed" This parable is unique to Mark. Because of Mar_4:14 we know this refers to the gospel message. Growth is a result of good seed and good soil. This is the divine and human aspects of covenant.
Mar_4:27-29 This may reflect salvation as a process (cf. 1Co_1:18; 1Co_15:2; 2Co_2:15; 2Pe_3:18). This parable describes the mysterious and amazing growth of faith in the life of the fallen children of Adam. The goal is fruit!
