Hallo, Jakester,
I think we are both interpreting Jesus' parable in a similar way by using different words.
Your explanation corresponds, of course, to what Matthew is saying, while mine only pretends to explain the parable in a simpler way.
In Jesus’ parable the farmer is supposed to be the Son of Man; the fields correspond to our World. The wheat is the sons of the Kingdom of God, i.e. those who deserve to go there because of their good deeds or because they have sincerely repented from their sins.
Satan, of course, is the enemy who plants the weeds in the middle of the wheat to destroy it. Therefore, the weeds are Satan’s sons. Who are Satan’s sons? Those who through their bad deeds fit that description!
The Harvest correlates with the end of time, or Judgment Day, when the Harvesters (the Angels) will come to reap the crop. It will be then when the Harvesters will separate the weeds and throw them to the fire while the wheat will shine in the Kingdom of God...
Who will then be represented by the weeds? Those who have fallen under the influence of Satan because of their behavior and bad deeds down here. And it will be they who will weep and gnash and clench their teeth.
And the final meaning of the parable is that we shall have to wait until the Judgment Day for the harvesters to separate the wheat from the weeds.
Why separating the wheat from the weeds before harvest is so difficult? Because the sprouts look alike, and it would be possible to severely damage the good plants.
Probably, Jesus’ intention when pointing out to this possibility was that the “weeds” (Satan’s sons) were to be found (and still are so much so) muddle up in the same churches and congregations together with the “wheat” (the sons of the Kingdom), which means spread all over the world.
This is precisely why we have to await until the “harvesting time” to avoid damaging the wheat while doing away with the weeds.
Now then, I think you will agree that it is up to us to decide whether we want to serve in the ranges of the wheat crops owing to our good deeds or prefer, instead, start practicing the gnashing and grinding of teeth in Satan’s militia as a consequence of our bad deeds.
Our GOD is the GOD of love but at the harvest time, he collects the weeds and ties them in bundles to be burned. Then HE gathers the wheat and brings it into his barn (verse 30).
What I tried to emphasize in my previous post was that the only way to benefit of GOD’s love for us is by corresponding to it with our deeds. That’s all.
