Fishing net
shown in American Standard Version
This parable shows how many people will be attracted to the Word of God, but states that not all who are brought into the visible service of God will be converted. A day will come when the good will be separated from the bad.
Mt 13:47-50
47 Again, the kingdom of heaven is like unto a net, that was cast into the sea, and gathered of every kind:
48 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.
49 So shall it be in the end of the world: the angels shall come forth, and sever the wicked from among the righteous,
50 and shall cast them into the furnace of fire: there shall be the weeping and the gnashing of teeth.
