Albert Barnes Commentary Matthew 13:47-51

"Again, the kingdom of heaven is like unto a net, that was cast into the sea, and gathered of every kind: which, when it was filled, they drew up on the beach; and they sat down, and gathered the good into vessels, but the bad they cast away. So shall it be in the end of the world: the angels shall come forth, and sever the wicked from among the righteous, and shall cast them into the furnace of fire: there shall be the weeping and the gnashing of teeth. Have ye understood all these things? They say unto him, Yea." — Matthew 13:47-51 (ASV)

The kingdom of heaven is like to a net, etc. This parable does not differ in meaning from that of the tares. The gospel is compared to a net, dragging along on the bottom of the lake, and collecting all—good and bad. The gospel may be expected to do the same. But in the end of the world, when the net is drawn in, the bad will be separated from the good: the one will be lost, and the other saved.

Our Saviour never fails to keep before our minds the great truth that there is to be a day of judgment, and that there will be a separation of the good and evil. He came to preach salvation; and it is a remarkable fact, also, that all the most striking accounts of hell, and of the sufferings of the damned, are from his lips. How does this agree with the representation of those who say that all will be saved?
