You hide your face, they are troubled: you take away their breath, they die, and return to their dust.
Read Chapter 104
Augustine of Hippo
AD 430
40. "When thou openest Thy hand, they shall all be filled with good" (ver. 28). What is it, O Lord, that Thou openest Thy hand? Christ is Thy hand. "To whom is the arm of the Lord revealed?" To whom it is revealed, unto him it is opened: for revelation is opening. "When Thou openest Thy hand, they shall all be filled with good." When Thou revealest Thy Christ, "they shall all be filled with good." But they have not good from themselves; this is oftentimes proved unto them. "When Thou hidest Thy face, they are troubled" (ver. 29). Many filled with good have attributed to themselves what they had, and have wished to boast as in their own righteousnesses, and have said to themselves, I am righteous; I am great: and have become self-complacent. Unto these the Apostle speaketh: "What hast thou, that thou didst not receive?" But God, wishing to prove unto man that whatever he hath he hath from Him, so that with good he may gain humility also, sometimes troubleth him; He turneth away His face from him, and he falleth into temptation; and He showeth him that his righteousness, and his walking aright, was only under His government. ...
41. But wherefore dost Thou do this? wherefore dost Thou hide Thy face, that they may be troubled? "Thou shalt take away their breath, and they shall fail." Their breath was their pride; they boast, they attribute things to themselves, they justify themselves. Hide, therefore, Thy face, that they may be troubled: take away their breath, and let them fail; let them cry unto Thee, "Hear me, O Lord, and that soon, for my spirit waxeth faint: hide not Thy face from me." "Thou shalt take away their breath, and they shall fail, and shall be turned to their dust." The man who repenteth of his sin discovereth himself, that he had not strength of himself; and doth confess unto God, saying, that he is earth and ashes. O proud one, thou art turned to thine own dust, thy breath hath been taken away; no longer dost thou boast thyself, no longer extol thyself, no longer justify thyself; thou seest that thou art made of dust, and when the Lord turneth away His face, thou hast fallen back into thine own dust. Pray, therefore, confess thy dust and thy weakness.
