Fear of God can be healthy or unhealthy. The healthy fear makes you afraid of being lost if you do not believe in God, while the unhealthy fear makes you afraid that God is going to take over if you surrender yourself to him. The healthy fear normally leads one to reconciliation with God, so it's the one to keep. And the unhealthy fear keeps you from growing closer to God, the fear you should not have. How intimate you are with the Lord is gauged by how comfortable you feel about him. Ideally, we should feel completely comfortable about our Lord, thus ready for whatever he wishes to do with us. This is perfect obedience.
