Matthew 16 is, for me, the climax of the book of Matthew. As Peter wrestle through the need for a personal savior for HIS sins, we see Jesus attack the problem with humanity: WE ARE SELFISH!!! The toughest pill to swallow is the answer that all humanity is searching for... if you want to find life, you are going to have to lay it down : ) It's good!
Visual: I used large children's lego blocks to build a fortress around myself. Then at different times, it gets broken down or blown away entirely at the end.
