Its use by Jesus is by far its most interesting aspect; for, in the Synoptists, at least, it is His watchword, or a comprehensive term for the whole of His teaching. Of this the ordinary reader of Scripture may hardly be aware, but it becomes evident and significant to the student. Thus, in
Mt 4:23, the commencement of the ministry is described in these words, "And Jesus went about in all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of disease and all manner of sickness among the people"; and, somewhat later, in
Lu 8:1, the expansion of His activity is described in the following terms, "And it came to pass soon afterwards, that he went about through cities and villages, preaching and bringing the good tidings of the kingdom of God, and with him the twelve." When the Twelve are sent forth by themselves, the purpose of
their mission is, in
Lu 9:2, given in these words, "And he sent them forth to preach the kingdom of God, and to heal the sick." In
Mt 13:11, the parables, which formed so large and prominent a portion of His teaching, are denominated collectively "the mysteries of the kingdom of heaven"; and it will be remembered how many of these commence with the phrase, "The kingdom of heaven is like."
