Fear of man is one thing we should not have. This is a snare as per the Bible. The fear of man brings a snare, But whoever trusts in the LORD shall be safe. (Proverbs 29:25 NKJV)
But fear of God has many virtues, benefits, and many blessings associated with it.
Fear of God is associated with Wisdom. The Bible states that fear of God is the beginning of Wisdom. Here is the specific verse. The fear of the LORD is the beginning of wisdom, And the knowledge of the Holy One is understanding. (Proverbs 9:10 NKJV)
