After 3 years of ministry, at the end of the 80-100 miles journey from Galilee to Jerusalem, Jesus crests the Mount of Olives on his way into the city, the crowd breaks into song, and he breaks into tears.
With one act of compassion, Jesus shows that the kingdom of heaven isn't coming with an army, heavy artillery strikes, etc to Make Israel Great Again... the kingdom is already here as Jesus takes things that seem insignificant and gives them massive significance.
