This SSATB choral anthem with piano accompaniment is based on Psalm 57 (verses 2,3, 5 & 7).  With its classical influence, the virtuosic piano introduction gives way to a chorale-like opening with two homophonic verses which include gospel harmonies. The piece then builds with "My heart is fixed...", a transition beginning in unison and expanding to a climactic German 6th chord in one phrase. Shifting to 12/8, the third section features Dr. Dee's signature "polyphonic vamp" in a majestic cacophony of interweaving phrases closing with three powerful call-and-response "Amens" led by the first sopranos.  
The accompaniment may be played as written as performed here by Dr. Shinae Kim with conductor Dr. Jan Taylor.  Or the pianist may include improvisation in a manner congruent with the idiom as shown here with the composer at the piano leading her Sacred Praise Chorale.
