"I have squandered the essence of my Father's riches as a prodigal..."

Icon of the Parable of the Prodigal Son (source)

  

I have squandered the essence of my Father's riches as a prodigal, and having consumed them all, I have come to dwell in a desert land of evil citizens, and I am no longer able to bear to dwell with them, so I return, crying out to You, O compassionate Father: I have sinned against heaven and before You, and I am no longer worthy to be called Your son. Make me as one of Your hired servants, O God, and have mercy on me.
-Idiomelon from the Sunday of the Prodigal Son in the Plagal of the Fourth Tone

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