Mark 4:26-29

Jesus moves from admonition to the Kingdom. The people who hear/do now receive from Jesus parables concerning the Kingdom. What is the Kingdom like? It is like wheat that grows and no one knows how. It's a mystery. The farmer waters it, but somehow G-D makes it grow.

The irony/twist in the parable is that Jesus has just expressed the need for His disciples to hear/do, and the parable He then tells relates to the fact that G-D alone makes the seed grow. G-D provides the action/growth, not the person.

So as you continue to prepare your soil (hear/obey), remember that G-D ultimately produces the crop and spreads His Kingdom. It's HIS Kingdom, and the forces of evil will not prevail against it.
