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.
