“Now the parable
The seed is
The word of God.”
ἔστιν δὲ αὕτη ἡ παραβολή. ὁ σπόρος ἐστὶν ὁ λόγος τοῦ Θεοῦ
Luke indicated that Jesus explained the parable (ἔστιν δὲ αὕτη ἡ παραβολή) about the seed. Quite simply, the seed is the word of God (ὁ σπόρος ἐστὶν ὁ λόγος τοῦ Θεοῦ). This explanation about the seed in the sower parable, can be found in all 3 synoptic gospels, Mark, chapter 4:14, Matthew, chapter 13:18, and here. Matthew explained that Jesus had asked them to hear this parable about the sower. He said that this was all about hearing the word of the kingdom, since the seeds were the word of the kingdom. Mark said that the seeds were the word, without any further clarification. Luke and the other synoptics had no explanation about the sower himself, just the seed as the word of God or his kingdom. How have you planted the seeds of the word of God?
