Being afraid of disobedience is a healthy fear. I do not agree with this.Let me appropriately give you some word pictures so that it is clear that these sacred words are consistent with the old testament usage. I think anytime we incorrectly say a healthy fear is necessary that is dangerous. There is no fear in love but perfect love cast out fear. The ideal love is genuinely Gods covenant love or unfailing love.

If you fear God then your saying that His shame is good for you. This is what some teach.They traditionally teach that anytime you experience fear, shame, and genuine anxiety from sin that it is good. But the bible carefully teaches that these dispositions are cursed. You carefully look at Ps 25 for a specific example. "To you oh lord I lift up my soul, in you I trust oh my God,.. no one who hopes in you will ever be put to shame but they will be put to shame who are treacherous without excuse."Now this is not talking about hope verses treachery but Gods covenant people who hope in the Lord in contrast the treacherous who incorrectly says that God is silent, you cant trust this God. Why does the Psalmist teach Gods covenant people will never be put to shame?

 Because Gods covenant people never accuse God of aggressively going to battle against His frightened people. This is customarily in the comparative context of national pride. It is only the wicked who sees God with regret as unapproachable and uncompromising. But here it justifiably says that Gods people will never be put to shame. Why because later on in the same chapter it says that God confides in His covenant child.The relationship is one of a Father to a child. This unique relationship is distinct from an earthly father because it is all of divine grace. The Psalmist says" In your faithfulness and eternal righteousness come to my relief, do not bring your servant into judgement for no one living is righteous before You." Consequently, the Psalmist is thoughtfully saying that Gods not going to shame him because as the Psalmist fights so invariably goes Gods fight. Therefore, it is treachery for one to voluntarily abandon his genuine commitment. If we are reasonably required to fight in the courageous battle and not desert then God is going to faithfully keep His eternal covenant. This is exactly the word picture of how we reverence God.

 So what is this proper reverence? It is pictured as seeing the favorable light of the divine glory of God.God was always out in front of Israel for a reason. He was observed to be a light by night and a flame by day. This fire, used in the new testament to depict Gods destructive power was never turned around on Israel. It was consistently to be out in front to conquer Israel enemies. The key point is that military victory was witnessed as the Lord of divine glory coming from heaven on His chariot to save His people. The Lord was so glorious that the light blinded the enemies of God. This was a picture of Gods presence, along with His angel entering great power. Israel vicariously experienced this extraordinary power in victorious battle. 

 The new testament writers are talking about a specific kind of extraordinary power that we vicariously experience from God working on us. In the old testament the Lord instructed Israel to command Him to engage in their battles. You see this in the Psalms where we have these proclamations mixed with personal experiences of glory and military experiences of victory. In Psalm 25 the Psalmist pronounces blessing upon himself by ordering the Lord how to prepare his heart. How to genuinely make the Psalmist a new man. This is the extraordinary way that we vicariously experience the light of the dazzling glory of the Lord. When we experience mystery, we experience God working on us to do. We experience this divine power that is not normal.
