Luke 6:44

On the thorns of this world the fig cannot be found, which as being better in its second fruit, is well fitted to be a similitude of the resurrection. Either because, as you read, The fig trees have put forth their green figs, (Cant. 2:13.) that is, the unripe and worthless fruit came first in the Synagogue. Or because our life is imperfect in the flesh, perfect in the resurrection, and therefore we ought to cast far from us worldly cares, which eat into the mind and scorch up the soul, that by diligent culture we may obtain the perfect fruits. This therefore has reference to the world and the resurrection, the next to the soul and the body, as it follows, Nor of a bramble bush gather they grapes. Either because no one living in sin obtains fruit to his soul, which like the grape nearest the ground is rotten, on the higher branches becomes ripe. Or because no one can escape the condemnations of the flesh, but he whom Christ has redeemed, Who as a grape hung on the tree.

(Hom. 42. in Matt.) But although the fruit is caused by the tree, yet it brings to us the knowledge of the tree, because the distinctive nature of the tree is made evident by the fruit, as it follows, For every tree is known by its fruit.

Or, I think the thorns and bramble are the cares of the world and the prickings of sin, but the figs and the grapes are the sweetness of a new life and the warmth of love, but the fig is not gathered from the thorns nor the grape from the bramble, because the mind still debased by the habits of the old man may pretend to, but cannot bring forth the fruits of the new man. But we must know, that as the fruitful palm tree is inclosed and supported by a hedge, and the thorn bearing fruit not its own, preserves it for the use of man, so the words and acts of the wicked wherein they serve the good are not done by the wicked themselves, but by the wisdom of God working upon them.

Each man's life also will be a criterion of his character. For not by extrinsic ornaments and pretended humility is the beauty of true happiness discovered, but by those things which a man does; of which he gives an illustration, adding, For of thorns men do not gather figs.
