Repent, for the kingdom of heaven is at hand.Jesus is the fulfillment of John’s message (Matt. 3:2, 11). The King is announcing the coming of His kingdom. Again, this repentance was a confession of sinfulness and a turning in faith to the only One who could give righteousness (Matt. 6:33; Rom. 5:17-18). Thekingdom here refers to the rule of God, brought to Earth through Jesus Christ, and exemplified in His people (Matt. 6:10).
