Jamieson, Fausset and Brown on Matthew 13:49

49. So shall it be at the end of the world, &c.--(See on Mt 13:42). We have said that each of these two parables holds forth the same truth under a slight diversity of aspect. What is that diversity? First, the bad, in the former parable, are represented as vile seed sown among the wheat by the enemy of souls; in the latter, as foul fish drawn forth out of the great sea of human beings by the Gospel net itself. Both are important truths--that the Gospel draws within its pale, and into the communion of the visible Church, multitudes who are Christians only in name; and that the injury thus done to the Church on earth is to be traced to the wicked one. But further, while the former parable gives chief prominence to the present mixture of good and bad, in the latter, the prominence is given to the future separation of the two classes.
