For the earth brings forth fruit of itself; first the blade, then the ear, after that the full grain in the ear.
All Commentaries on Mark 4:28 Go To Mark 4
Tertullian of Carthage
AD 220
Observe how the created order has advanced little by little toward fruitfulness. First comes the grain, and from the grain arises the shoot, and from the shoot emerges the shrub. From there the boughs and leaves gather strength, and the whole that we call a tree expands. Then follows the swelling of the germen, and from the germen bursts the flower, and from the flower the fruit opens. The fruit itself, primitive for a while, and unshapely, keeping the straight course of its development, is matured, little by little, to the full mellowness of its flavor. In just this way has righteousness grown in history. The proximate righteousness found in the created order is grounded in the holy God whose righteousness first emerged in a rudimentary stage as an undeveloped natural apprehension in the presence of the holy One. Then it advanced through the law and prophets to childhood. At long last through the gospel, God’s righteousness has been personally manifested with the vital energies of youth. Now through the paraclete, righteousness is being manifested in its mature stage.
