Jesus tells us what His Kingdom is like.
Some reject it, others receive it for a time, yet others receive it and bear fruit.
Speaking in parables fits with this truth.
There are weeds in the Kingdom, that won't be shown and rejected before the end.
The Kingdom expands and permeates (Gen 1:28), we know not how.
The Kingdom is a treasure, worth selling everything to get.
The Nazarenes reject Jesus. Will you?
