Psalm 95:1 “Come, let us sing for joy to the Lord; let us shout aloud to the Rock of our salvation.” No one shouts for joy during a time of depression.  No one sings aloud when they do not recognize the magnificence of our Glorious God.  No one invites others to join in this praise mentality unless they recognize God is to be praised.  We join our Psalmist in song and shouting praise to our loving Savior.
