“These are the seeds

Sown on the good soil.

They hear the word.

They accept it.

They bear fruit,

Thirty,

Sixty,

And a hundredfold.”

 

καὶ ἐκεῖνοί εἰσιν οἱ ἐπὶ τὴν γῆν τὴν καλὴν σπαρέντες, οἵτινες ἀκούουσιν τὸν λόγον καὶ παραδέχονται καὶ καρποφοροῦσιν ἓν τριάκοντα καὶ ἓν ἑξήκοντα καὶ ἓν ἑκατόν

 

This explanation of the good seeds can be found in all 3 synoptic gospels.  Mark indicated that Jesus said that the seeds sown on good soil (καὶ ἐκεῖνοί εἰσιν οἱ ἐπὶ τὴν γῆν τὴν καλὴν σπαρέντες) are the people who hear the word (οἵτινες ἀκούουσιν τὸν λόγον).  They accept it (καὶ παραδέχονται).  They then bear good fruit (καὶ καρποφοροῦσιν).  They yield either thirtyfold (ἓν τριάκοντα), sixtyfold (καὶ ἓν ἑξήκοντα), or a hundredfold (καὶ ἓν ἑκατόν).  Mathew, chapter 13:23, has the reverse order of 100, 60, and 30, while Luke, chapter 8:15, has no number on the fruits of the harvest.  Only about 25% of the seeds sown were effective.  Thus, only about 25% of the people hearing the word of the kingdom will follow it.  There had to be good circumstances or pre-depositions to hearing and understanding for the word or the seed to be effective.  The seeds or the word that fell on the path, on the rocky ground, or the thorns were ineffective.  However, even among the effective seeds that were on good soil, the word would have different results.  Some would yield 30 times, some 60, and some 100.  There was no magic formula.  The circumstances among the good hearers would also bring about a variety of responses and effectiveness.
