3 “Hear my prayer, O Lord: and let my crying come unto You”. “Hear my prayer, O Lord,” is the same as, “Let my crying come unto You:” the feeling of the suppliant is shown by the repetition. “Turn not Your face away from me.” When did God turn away His Face from His Son? When did the Father turn away His Face from Christ? But for the sake of the poverty of my members, “Turn not away Your face from me: whatsoever day I am troubled, incline Your ear unto me”....You are in trouble this day, I am in trouble; another is in trouble tomorrow, I am in trouble; after this generation other descendants, who succeed your descendants, are in trouble, I am in trouble; down to the end of the world, whoever are in trouble in My body, I am in trouble....Peter prayed, Paul prayed, the rest of the Apostles prayed; the faithful prayed in those times, the faithful prayed in the following times, the faithful prayed in the times of the Martyrs, the faithful pray in our times, the faithful will pray in the times of our descendants.
“Right soon:” for I now ask that which You are willing to grant. I ask not earthly things, as an earthly man; but redeemed at last from my former captivity, I long for the kingdom of heaven; “Hear me right soon:” for it is only to such a longing that You have said, “Even while You are speaking, I will say, Here I am.” Wherefore do you call? In what tribulation? In what want? O poor one, before the gate of God all-rich, in what longing do you beg? From what destitution do you ask relief? From what want do you knock, that it may be opened unto you?
