A lot of people fear a lot of things, but Isaiah makes it clear in today's reading that there's really only one thing we should fear: the Lord.  See, when we recognize that God is holy and that He is sovereign over all, there's nothing we have to be afraid of… as long as we fear Him.  To fear God means to view Him with a proper perspective – the perspective that He knows all, understands all, and controls all.  With the Israelites, rather than being afraid of impending attacks, they needed to be afraid of offending God.  If they were fully submitted to Him, then He was prepared to protect them.  In many ways, the same is true for us.  When we walk down the path of submission to God and fearing Him only, then the other issues in our lives fall in line.  We don't have to worry about the loss of a job when we know that God is our Provider.  We don't have to fear people who speak badly about us when we know that God is our Defender.  So the question you need to consider is: what or whom do you fear?  And if what you fear isn't God, could placing your fear in God take away the other fears that you have?
