Why did Simon say going to the synagogue was "none too soon" in The Bronze Bow.

In Chapter 4 of The Bronze Bow we
find Daniel starting to wish he had never come down from the mountains.  His friend
Simon comes by and asks Daniel to come to the synagogue with him because it is the
Sabbath and he wants Daniel to hear a man speak.  Daniel tells Simon that he hasn't been
to the synagogue for five years.  He says that one more Sabbath won't
matter. 

"On
the contrary," Simon answered with a smile. "Today is none too
soon."

Simon is letting
Daniel know that it is about time he visit the synagogue exactly because it has been
five years.  Simon feels that because Daniel has avoided his spritual growth and the
laws of their religion it is time for Daniel to go to the synagogue without wasting
another Sabbath.
