The beginning of wisdom....
According to both Psalm 111:10 and Proverbs 9:10, fear of the Lord (read fear as "awe" not "being frightened of") is the beginning of wisdom. Proverbs 1:7 says that "fear of the Lord is the beginning of knowledge; fools despise wisdom and instruction." It is an open question as to whether wisdom can be equated with knowledge.
On the other hand, according to a Chinese proverb, the beginning of wisdom is to call things by their right names.
I rather like all of these proverbs and like the ideas intertwined here - wisdom, knowledge, attitude, actions. Fortunately, they don't have to be considered in either-or fashion. God is first, unquestionably. But this whole "calling things by their right names" thing is pretty good. Maybe we could say that's maturity.... but is being mature equal to being wise?
