It's about

 

as straight forward 

as it gets:

Matthew 13:47-50

The Parable of the Net

 “Once again, the kingdom of heaven is like a net that was let down into the lake and caught all kinds of fish. 48 When it was full, the fishermen pulled it up on the shore. Then they sat down and collected the good fish in baskets, but threw the bad away. 

(That never gets accounted for 

in the doctrine of the pretribulation "rapture". 

Never.)

49 This is how it will be at the end of the age. 

The angels will come 

and separate the wicked from the righteous 

50 and throw them into the blazing furnace, where there will be weeping and gnashing of teeth.

(Better: from among the righteous

as in the Scofield bible

See the good and bad fish example above.)

Scofield Notes

(13:47) The parable of the net (lit. "dragnet") presents another view from that of the wheat and tares, 

(It's another view alright

its a further refining.

Its much more:

Separating the Wheat from Chaff

(Two different parts of the same thing)

Matthew 3:12

Whose fan is in his hand, 

and he will throughly purge his floor, 

and gather his wheat into the garner; 

but he will burn up the chaff with unquenchable fire.

than it is

Separating the Wheat from the Tares.

(Separating two different things 

from each other, which has to come first.)

Matthew 13:30.

Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn.

So first the separation 

of wheat from tares (weeds).

Then a further refining is accomplished:

The Wheat from chaff

Matthew 3:12

12 Whose fan is in his hand, and he will throughly purge his floor, and gather his wheat into the garner; but he will burn up the chaff with unquenchable fire.

Back to Scofield notes:)

"...that of the mystery of the kingdom as the sphere of profession, with this difference: there Satan was the active agent; 

here the admixture is more the result of the tendency of a movement to gather to itself that which is not really of it. 

(He might as well have been talking about

MAGA Christians.)

"The kingdom of heaven is like a net which, cast into the sea of humanity, gathers of every kind, good and bad. These remain to-gether in the net (v. 49) and not merely in the sea, until the end of the age. It is not even a converted net, much less a converted sea. Much violence has been done to sound exegesis by the notion that the world is to be converted in this age. Against that notion stands our Lord's own interpretation of the parables of the sower, the wheat and tares, and the net.

Such, then, is the mystery form of the kingdom (see Mt.3:2, note; 6:33, note). 

It is the sphere of Christian profession during this age. 

It is a mingled body of true and false, 

wheat and tares, good and bad. 

It is defiled by formalism, doubt, 

and worldliness. 

But within it Christ sees the true children of the true kingdom who, at the end, are to "shine forth as the sun." In the great field, the world, He sees His treasure that He redeems for His own through His cross. Thus, in this aspect of the kingdom, He sees the Church, His body and bride composed of believing Israelites and Gentiles, and for joy sells all that He has (2 Cor.8:9) and buys the field, the treasure, and the pearl.

The whole point being:

49 This is how it will be 

at the end of the age. 

The angels will come 

and separate 

the wicked from (among) 

the righteous.

Revelation 9:4

And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads.

Might wanna get in your right mind 

and understand you are walking around 

in God's creation

and that he is sovereign over all.

Maranatha Lord Jesus.
