Now in those days John the Baptist came, preaching in the wilderness of Judea, saying, âRepent, for the kingdom of heaven is at hand.â (Matthew 3:1)Although the precise phrase is not found there, the kingdom of heaven is basically an Old Testament concept. David declares that âthe Lord is King forever and everâ (Ps. 10:16; cf. 29:10), that His kingdom is everlasting, and that His dominion âendures throughout all generationsâ (Ps. 145:13). Daniel speaks of âthe God of heaven [who] will set up a kingdom which will never be destroyedâ (Dan. 2.:44; cf. Ezek. 37:25), a âkingdom [that] is an everlasting kingdomâ (Dan. 4:3). The God of heaven is the King of heaven, and the heavenly kingdom is God's kingdom.Matthew uses the phrase kingdom of heaven thirty-two times, and is the only gospel writer who uses it at all. The other three use âthe kingdom of God.â It is probable that Matthew used kingdom of heaven because it was more understandable to his primarily Jewish readers.
