Ecclesiastes 12:13 Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
God isn't asking you to walk in fear or He will take some kind of celestial ball bat and beat you senseless. He wants you to live a life that He can use and bless. He wants you to walk in awe of Him. He wants your heart to be so filled with respect that you will die rather than dishonor Him and His name.
You will live no better than the level at which you honor and reverence God. If you see the Lord as being high and holy, as being a God of judgment, One Who hates sin; then you will live like you believe it.
But If you believe that God just winks at sin, and He might not really judge the world, then you will live at a much lower level. Your life will tell the world what you think of God.
