Psalm 4

Psalm 4
English Standard Version (ESV)

  I heard a preacher recently say that joy is the flag that flies in the castle of our hearts when the king is at home.  I love that image -- that joy is the evidence we display when Christ is King, because when he reigns in our hearts, we can have peace and joy and fullness.  There is no joy like the joy we get in Christ, for his joy is complete and comes with the power of God, and his joy has promised to endure, no matter what the world may throw at it.  His joy is eternal, and we shall reign with Christ in the heart of it.
  Joy can be challenging, but remember that it's deeper than happiness.  Joy rests within us and can be steadfast in the face of the waves and the storms.  Joy endures.
