The fear of the Lord is the beginning of knowledge, but fools despise wisdom and instruction. ~ Proverbs 1:7
Fear drives people toward bad decisions and it prevents people from making the right decisons.
Fearing God is not like fearing the unknown or difficult circumstances. Fearing God means you respect His authority, His truth, and His instruction.
We should be more afraid of living separated from God than to face God's purifying truth. Seek His truth and you'll find knowledge that will guide your life.
