Matthew 3:2 - Wesley's Explanatory Notes

The kingdom of heaven, and the kingdom of God, are but two phrases for the same thing. They mean, not barely a future happy state, in heaven, but a state to be enjoyed on earth: the proper disposition for the glory of heaven, rather than the possession of it. Is at hand — As if he had said, God is about to erect that kingdom, spoken of by Daniel Daniel 2:44; Daniel 7:13-14; the kingdom of the God of heaven. It properly signifies here, the Gospel dispensation, in which subjects were to be gathered to God by his Son, and a society to be formed, which was to subsist first on earth, and afterward with God in glory. In some places of Scripture, the phrase more particularly denotes the state of it on earth: in ,others, it signifies only the state of glory: but it generally includes both. The Jews understood it of a temporal kingdom, the seat of which they supposed would be Jerusalem; and the expected sovereign of this kingdom they learned from Daniel to call the Son of man. Both John the Baptist and Christ took up that phrase, the kingdom of heaven, as they found it, and gradually taught the Jews (though greatly unwilling to learn) to understand it right. The very demand of repentance, as previous to it, showed it was a spiritual kingdom, and that no wicked man, how politic, brave, or learned soever, could possibly be a subject of it.
