Luke 17:21

17:21 nor will they say, ‘Look, here it is!’ or ‘There!’ For indeed, the kingdom of God is ¹  in your midst.” ² 

Mark 4:26

The Parable of the Growing Seed

4:26 He also said, “The kingdom of God is like someone who spreads seed on the ground.

Mark 4:30-34

The Parable of the Mustard Seed

4:30 He also asked, “To what can we compare the kingdom of God, or what parable can we use to present it? 4:31 It is like a mustard seed ³  that when sown in the ground, even though it is the smallest of all the seeds in the ground – 4:32 when it is sown, it grows up, ⁴  becomes the greatest of all garden plants, and grows large branches so that the wild birds ⁵  can nest in its shade.” ⁶ 

The Use of Parables

4:33 So ⁷  with many parables like these, he spoke the word to them, as they were able to hear. 4:34 He did not speak to them without a parable. But privately he explained everything to his own disciples.

[17:21]  ¹ tn This is a present tense in the Greek text. In contrast to waiting and looking for the kingdom, it is now available.

[17:21]  ² tn This is a far better translation than “in you.” Jesus would never tell the hostile Pharisees that the kingdom was inside them. The reference is to Jesus present in their midst. He brings the kingdom. Another possible translation would be “in your grasp.” For further discussion and options, see D. L. Bock, Luke (BECNT), 2:1414-19.

[4:31]  ³ sn Mustard seeds are known for their tiny size.

[4:32]  ⁴ tn Mark 4:31-32 is fairly awkward in Greek. Literally the sentence reads as follows: “As a mustard seed, which when sown in the earth, being the smallest of all the seeds in the earth, and when it is sown, it grows up…” The structure has been rendered in more idiomatic English, although some of the awkward structure has been retained for rhetorical effect.

[4:32]  ⁵ tn Grk “the birds of the sky” or “the birds of the heaven”; the Greek word οὐρανός (ouranos) may be translated either “sky” or “heaven,” depending on the context. The idiomatic expression “birds of the sky” refers to wild birds as opposed to domesticated fowl (cf. BDAG 809 s.v. πετεινόν).

[4:32]  ⁶ sn The point of the parable seems to be that while the kingdom of God may appear to have insignificant and unnoticeable beginnings (i.e., in the ministry of Jesus), it will someday (i.e., at the second advent) be great and quite expansive. The kingdom, however, is not to be equated with the church, but rather the church is an expression of the kingdom. Also, there is important OT background in the image of the mustard seed that grew and became a tree: Ezek 17:22-24 pictures the reemergence of the Davidic house where people can find calm and shelter. Like the mustard seed, it would start out small but grow to significant size.

[4:33]  ⁷ tn Grk “And.” Here καί (kai) has been translated as “so” to indicate the implied result of previous action(s) in the narrative.
