from Starck's Advent Evening Prayer

We have nothing to give You; we are not able in the least to repay You for rescuing us from the lost condition in which we found ourselves by nature and for setting us free from the bonds of death that held us fast.  All these blessings came to us because Your Son became man.  Your love has no equal - it passes all understanding!  We can do nothing but humbly thank You, praise You, and magnify You.  This is the only tribute by which our hearts can express their affection for You.
