ibid, he sees repentance as the key;
While Matthew 10:5–7 does not mention “repent,” repentance was part of the message. For in Matthew 11:20 we are told, “Then He [Jesus] began to denounce the cities in which most of His miracles were done, because they did not repent.” So the message of the kingdom to the cities of Israel was offered with repentance as a necessary condition. The prophesied kingdom was on the brink. The words “at hand” mean the kingdom was impending. The kingdom was near so Israel needed to be ready; the people needed to repent. It would not be bestowed simply based on ethnicity. Repentance was the prerequisite for entrance into the kingdom. With John 3:3 Jesus declared, “unless one is born again he cannot see the kingdom of God.” While there is a close relationship between salvation and the kingdom, the two are not the same thing. We cannot say “salvation is the kingdom,” or “the kingdom is salvation.” The kingdom of God is a broader concept than human salvation. One must be saved in order to enter the kingdom. Thus, salvation is the qualification for entrance into the kingdom. The statement, “Repent for the kingdom of heaven is at hand,” is reliant upon the informing theology of passages like Leviticus 26:40–45; Deuteronomy 4:25–31; Deuteronomy 30:1–10; Jeremiah 3:12–18; Jeremiah 4:1–2; and 2 Chronicles 7:13– 14, namely that Israel’s repentance brings Israel’s restoration to Abrahamic covenant blessings and the kingdom of God. The word “Repent” coincides with the Hebrew term”—“return (shub). Thus, the call to repent for the kingdom is at hand is a call to Israel to return to the Lord so they can experience kingdom blessings.11
