Mark 4:1-2

Jesus goes from having a meal in a house to having to teach from a boat because the crowds were so large. Not bad. I imagine the acoustics worked well also. (And notice that the Teacher is sitting, while the crowds are probably standing.)

And because of this massive crowd, He decides to speak to the people clearly to allow them to understand the basic message of G-D's grace...right? Why does He NOT do that? Why instead does He speak to the mass of people in parables? What is it about Isaiah 6 (verse 12) that He wants to get across?

I will provide, L-RD willing, some thoughts on why Jesus speaks this way to the crowds when I get down to that verse in my memorization.

In the meantime, what implications do these verses have on our lives and churches? Should our vocabulary be particular? Should our actions and liturgy (church service) be one that is comprehended by all, or should there be a tinge of mystery within it?
