“But when the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come.”
Mark 4:29 — Greek Interlinear
Church Fathers on Mark 4:29
The kingdom of God is the Church, which is ruled by God, and herself rules over men, and treads down the powers which are contrary to her, and all wickedness.
Or else Christ sleeps, that is, ascends into heaven, where, though He seem to sleep, yet He rises by night, when through temptations He raises us up to the knowledge of Himself; and in the day time, when on account of our prayers, He sets in order our salvation.
Or else, Man casts seed into the ground, when he places a good intention in his heart; and he sleeps, when he already rests in the hope which attends on a good work. But he rises night and day, because he advances amidst prosperity and adversity, though he knows it not, for he is as yet unable to measure his increase, and yet virtue, once conceived, goes on increasing.
