For me the juxtaposition of signs speaks to our struggles as humans relating to God. We want to see God at work. We want and expect God to do great things – but at the same time we impose limits. Frequently we want him to go slowly; maybe he should observe a speed limit. Sometimes we don’t want to go where he wants to take us, so we try to convince him that there is no through traffic. If all else fails we just park and refuse to budge.
Reminds me a bit of the sentiments of Father Fitz: All you have to do is ask.
