Psalm 27 is the Responsorial Psalm for Mass today. Verses 1 & 4 are so beautiful that I'll just quote them here without comment.
"The LORD is my light and my salvation; whom should I fear? The LORD is my life's refuge; of whom should I be afraid? One thing I ask of the LORD; this I seek: To dwell in the house of the LORD all the days of my life, that I may gaze on the loveliness of the LORD and contemplate his temple."
