The following prayer captured my heart from the moment I first read it and has stayed with me ever since.
You have taken me captive with longing for You, O Christ,
And have transformed me with Your divine love.
Burn up my sins with the fire of Your Spirit,
And count me worthy to take my fill of delight in You;
That dancing with joy, I may magnify Your two Comings.
Pre-Communion prayer by St. John of Damascus
