Peace should never be the end goal for the believer, but a result of a goal. Look at Jesus as an example: the founder and perfecter of our faith who for the joy set before him endured the cross (Heb. 12:2). The goal was obedience and glory to God the Father. The result was glory, honor, joy, and peace.
It’s actually a huge grace for God to allow his children to experience fear – otherwise we might be overwhelmingly passionless, stupidly courageous, proud, and arrogant.
