“The Kingdom of Heaven has drawn near.” This message was spoken by both John and Jesus. Neither of them knew that the coming of the Kingdom of Heaven would be more than 2,000 years in the future. The parallel passage to Matthew 4:17 is Mark 1:15 (see commentary on Mark 1:15).
[For more on the many different ways that Jesus said the Kingdom of God was coming soon, see commentary on Matt. 16:28. For more on what Christ’s kingdom on earth, the “Kingdom of God,” will be like, see Appendix 3, “Christ’s Future Kingdom on Earth”].
