You are close, but have not put it together.You still assume that the “thirty fold, sixty fold, one hundredfold” is chronological, but the scriptures say a crop, not successive crops throughout an expanse of time.
Matthew 13:8
Still other seed fell on good soil and produced a crop—a hundredfold, sixtyfold, or thirtyfold.
Scripture does not say “thirty fold, then sixty fold, and later one hundredfold”.
The different yields occur at one harvest in one moment of time.
Mark 4:20
And these are they which are sown on good ground, such as hear the Word and receive it and bring forth fruit: some thirtyfold, some sixty, and some a hundred.
So in Mark the different yields are produced by “such as hear the Word and receive it”, thus different individuals produce different yields.
The difference that you are not accounting for is "but each one in his own order."
Indeed, you are correct to say that there is only one crop--but when I have said that to many here, explaining that the difference is the eternal (timeless, one-time) perspective of God, compared with the times of this world where the crop comes "but each one in his own order" according to Paul--most have denied both. Both of which many here, including yourself, have rejected, when all I did was repeat what is written but never considered properly.
So, to deny the one and also deny the other--which you have now done on both accounts--is to deny yourself and God who set them both before the church to be "rightly divided"--not categorically denied.
