Psalm 3:3-6

But You, O Lord, are a shield for me, My glory (and my honor), and the One who lifts my head.  With my voice I was crying to the Lord, and He answered me from His holy mountain.  I lay down and slept (safely); I awakened, for the Lord sustains me.  I will not be intimidated or afraid of the ten thousands who have set themselves against me all around.  

Our strength and power in this life come from God.  God is the one who lifts our heads when we are downcast.  We need to raise our heads and lift our voices filled with the word and walk in our covenant rights.  A silent believer is a defeated believer, and we are more than conquers through Jesus Christ.  Be encouraged and strengthened with the word of God.
