When you look through the Scriptures, you'll find two different forms of fear mentioned. One kind of fear is healthy and good. The other is a detriment to our life and faith.
The healthy kind of fear that is spoken of in the Scriptures is the "fear of God." When the word fear is being used in that context, it's speaking about "reverence" or "awe." The fear of God is a healthy respect for God that acknowledges His great power and authority. We're encouraged to live in, or practice that kind of fear because it's healthy.
The other kind of fear that's spoken of in Scripture is an unhealthy terror or dread related to people or circumstances that we don't have the ability to control. That's not a healthy fear to live in, because it influences us to forget about God's sovereign ability to work out His will in all kinds of circumstances. That kind of fear produces anxiety in our lives because it makes us think we have to try to bring under control the kind of things that only God can control.
With that in mind, how can we give up the pattern of living with unhealthy fear? What do we need to know and what do we need to practice in order to live a life of faith, not fear?
