"The Fear of the Lord is the beginning of all wisdom." (Proverbs 1:7).
It's not just something you can naturally do. It's something earned by prayer and study of the Bible. Let's continue with Proverbs.
"My son, if you receive my words, and treasure my commandments within you" (2:1)
If you accept the Bible as the authoritative word of God and you delight in obeying His law.
"So that you incline your ear to wisdom, and apply your heart to understanding" (2:2)
If you listen for wisdom and set your goal to obtain it, using discretion to determin what is wisdom and what is foolishness,
"Yes, if you cry out for discernment, and lift up your voice for understanding" (2:3)
Prayer to God for wisdom and understanding,
"If you seek her as silver, and search her as for hidden treasures" (2:4)
If you work as hard as men work to find gold,
"Then you will understand the fear of the Lord, and find the knowledge of God." (2:5)
The fear of God is the beginning of all knowledge, and once these things are done, only then will you actually understand it.
Let me witness my personal experience with this, and I'll greatly simplify it so this isn't a huge post. I lived in sin all my life. One day God put the thought in my heart, "God may condemn me to eternal hell." Of course, this scared me, so I began to search the Scriptures to understand more about God. The more I understood Him, the more I loved Him. However, the more I understood Him, the more I feared Him! Our God is a mighty, allpowerful, sovereign Lord of heaven and earth, and your soul is in His hands. The Bible makes it clear that He condemns many many people to hell and saves only a few. This brings much fear to me!
Now because of this fear, I seek to understand the sovereign God that is in control of my life and soul. Yes, the fear of the Lord is most defently the beginning of wisdom, and to know God is eternal life (John 17:3).
I'm disagree with the thought that we are not to be terrified by our almighty God. It is certainly not a sin, and I believe that is the heart of what the fear of the Lord means--a true trembling fear. Of course, this fear evolves into awe and amazment when one understands that the love of God was set upon him. No, I'm afraid I'd have the same reaction as Moses had when He saw God on Mt. Sinai (Heb. 12:21).
There are many Proverbs and Psalms that obtain to the fear of God.
