Matthew 3:2 (1-12) - Repent, for the kingdom of heaven is at hand.
(v.8) Therefore bear fruit in keeping with repentance.
John the Baptizer is telling us that we need to bear fruit for the kingdom of God.
Matthew 21:43 (33-43) - Therefore I say to you, the kingdom of God will be taken away from you and given to a people, producing the fruit of it.
Vineyard = The kingdom of God
Vine Growers = Chief Priests and Pharisees
Slaves = Prophets proclaiming repentance
Son = Gods only begotten Son, Jesus
The kingdom of heaven is only for those producing the fruit of it. This fruit comes by the way of repentance first.
Changing our mind and what we think is the right way to what Gods way is. This is the only way to start bearing good fruit. And that starts by seeking God by reading His word.
The context of Matthew 21:33 starts off "Listen to another parable." Did you know that all the time Jesus talked about the kingdom of heaven or the kingdom of God, it was spoken in parables to the crowds? Not ONCE does Jesus reveal what the Kingdom of Heaven/God is in the gospels. It is talked about over 80 times yet, not explained what it is. But it is the first reason John the Baptist says we have to repent for. Jesus says the same thing.
Do you hear about the kingdom of God in church today? If so, what do you think it is?
