Theophylact of Ohrid
Catena Aurea · Markusevangelium 4
Mk 4, Verses 26–29English original
And he said, So is the kingdom of God, as if a man should cast seed into the ground; And should sleep, and rise night and day, and the seed should spring and grow up, he knoweth not how. For the earth bringeth forth fruit of herself; first the blade, then the ear, after that the full corn in the ear. But when the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come.
For we put forth the blade, when we shew a principle of good; then the ear, when we can resist temptations; then comes the fruit, when a man works something perfect. It goes on: and when it has brought forth the fruit, immediately he sendeth the sickle, because the harvest is come.
