When a person says something, normally we immediately take into consideration  who the person is that is speaking. When God is behind the person telling us then we can have more confidence in what is being spoken.  In this devotion Elisha the great prophet is telling his servant not to be afraid because there are more with them than those who are opposed.  Elisha asks God for a miracle so his servant would be able to understand.  Sometimes we need a similar miracle to understand how great our God is and how mighty He is in taking care of us.
