25 Here καί (kai) has not been translated because of differences between Greek and English style.

27 The kingdom of God is a major theme of Jesus. It is a realm in which Jesus rules and to which those who trust him belong. See Luke 6:20; 11:20; 17:20–21.
28 Or “come near to you,” suggesting the approach (but not arrival) of the kingdom. But the combination of the perfect tense of ἐγγίζω (engizō) with the preposition ἐπί (epi) most likely suggests that the sense is “has come upon” (see ἐγγίζω 2; W. R. Hutton, “The Kingdom of God Has Come,” 64 [Dec 1952]: 89–91; and D. L. Bock, Luke [], 2:; cf. also “is at hand for you”). These passages argue that a key element of the kingdom is its ability to overcome the power of Satan and those elements in the creation that oppose humanity. Confirmation of this understanding comes in v. 18 and in Luke 11:14–23, especially the parable of vv. 21–23.
