"O Lord Pantocrator, I see what tears can accomplish..."

The Prayer of Hezekiah (source)

  
O Lord Pantocrator, I see what tears can accomplish, for Hezekiah was lifted up from the gates of death, having been delivered from many years of sin, while the Publican was justified above the Pharisee, and I entreat you to number me among them and have mercy on me.
-Doxastikon of the Stichera from the Sunday of the Publican and the Pharisee

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
