To be honest, I don't really care for Voltaire. This being said, I love his quote and agree with it whole-heartedly. Common sense is in short supply these days.
James write about this in the New Testament: If any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given him.
James reminds me that one of my most fervent prayers should be for wisdom as I seek to live out my faith... not only as a pastor, but also as a husband, father, son, brother, friend, neighbor, and citizen.
I imagine that you are the same. Like me, right now you can use all the wisdom you can find to live out your faith in your daily vocations.
For the Christian, wisdom begins with the fear of the Lord. This refrain is found in several places in Scripture, especially the book of Proverbs: The fear of the Lord is the beginning of knowledge, but fools despise wisdom and discipline.
[Note: in Biblical terms, a fool is someone who ignores, abandons, or rejects God's commands and corrective actions.]
Trust in the Lord with all your heart and lean not on your own understanding. In all your ways acknowledge him, and he will make your paths straight. Do not be wise in your own eyes; fear the Lord and shun evil.
So declares Solomon in Proverbs chapter 3.
Biblical wisdom has nothing to do with graduating from Harvard or Yale. Nor does it mean having a degree from a seminary. The same goes for belonging to Mensa.
The fear of the Lord is the beginning of wisdom, all who follow his precepts have good understanding. (Psalm 111:10)
The fear of the Lord is the beginning of wisdom, and knowledge of the Holy One is understanding. (Proverbs 9:10)
The fear of the Lord teaches a man wisdom, and humility comes before honor. (Proverbs 13:33)
How much better to get wisdom than gold, to choose understanding rather than silver. (Proverbs 16:16)
