The kingdom of heaven

The kingdom is teaching

Mt 13:33 Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened.

The kingdom is like leaven, and leaven is teaching: see Leaven is teaching

The kingdom is the new Jerusalem

Re 3:12 Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, [which is] new Jerusalem, which cometh down out of heaven from my God: and [I will write upon him] my new name.

Re 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.

Jerusalem is the teaching of peace
