This illustrate that every choice we make (each stick, each lego) affects our destiny/future/testimony.

I have 2 small drawstring bags, one filled with Lego’s and one filled with junk (broken Popsicle sticks, small rocks, broken hunks of concrete, twigs, etc.)
I have 2 children each come to the front of the room, in view of all, and build a house out of their materials, so we can then compare the different "houses".
If we make a rash of good choices (Lego's), we have a strong, healthy, safe future and life. If we make poor choices (which lead to less alternatives and more poor choices), then we end up with a shaky future that won't take more than one shake to send it toppling to the ground.
