What's the Kingdom Like?

(from Mark 4:30-33 )

What shall we say the kingdom's like,
What words or phrases light the light?
It's like the smallest seed of all,
A mustard seed grows till it's ten feet tall

The kingdom spreads from the tiniest plant,
With branches extending all over the land,
People can shade under a mustard tree,
So the kingdom is just like that, you see?

In ways like this our Saviour spoke,
To make things plain to ordinary folks,
Showing all what God's kingdom is,
Can't fail to see what He knew was His.
