Origen
Catena Aurea · Matthäusevangelium 24
Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh: So likewise ye, when ye shall see all these things, know that it is near, even at the doors. Verily I say unto you, This generation shall not pass, till all these things be fulfilled. Heaven and earth shall pass away, but my words shall not pass away.
As the fig has its vital powers torpid within it through the season of winter, but when that is past its branches become tender by those very powers and put forth leaves; so the world and all those who are saved had before Christ’s coming their vital energies dormant within them as in a season of winter. Christ’s Spirit breathing upon them makes the branches of their hearts soft and tender, and that which wasdormant within burgeons into leaf, and makes shew of fruit. To such the summer and the coming of the glory of the Word of God is nigh at hand.
