Notice the good fish and the bad fish, in Matthew 13:47-51, were in the net together. The world is not caught in the dragnet of the kingdom of heaven; they remain in the world.
The “fish” that are caught are those who respond to the gospel—the evangelistic “catch.” They remain together until the Day of Judgment.
Matthew 13:47 “Again, the kingdom of heaven is like a dragnet that was cast into the sea and gathered some of every kind,
48 “which, when it was full, they drew to shore; and they sat down and gathered the good into vessels, but threw the bad away.
49 “So it will be at the end of the age. The angels will come forth, separate the wicked from among the just,
50 “and cast them into the furnace of fire. There will be wailing and gnashing of teeth.”
