The Incarnation is already the beginning of the coming of Christ's Kingdom, which includes, but is not ideentical with, the Kingdom of Heaven or of God. The preaching of the “Gospel of the Kingdom” therefore opens with the same good news announced by the Forerunner and by Christ: “the Kingdom of God is at hand.” The Kingdom of Heaven (= the Kingdom of God)
