My church has been using a video by Dr. Edward Sri to explain the changes to the Mass that start with Advent. This resonated with me:
A man walked a tightrope across Niagara Falls. The crowd cheered below him.
Reaching the other side, he heard their accolades and asked them, "Do you believe I can walk back blindfolded?"
"Yes!" they cheered.
"Do you believe I can walk back blindfolded and pushing a wheelbarrow?"
"Do you believe I can walk back blindfolded, pushing a wheel chair, and have someone sitting in the wheelbarrow?!"
"Great - who wants to sit in the wheelbarrow first?"
The point was to illustrate that our belief, as recited in the Creed, is both one of intellectual belief AND placing all trust in God - in a sense, getting in His wheelbarrow.
Are you there yet?
