Psalms 63:7

"Because Thou has become my helper." For unless God aid our good works, they cannot be accomplished by us. And worthy things we ought to work: that is, as though in the light, since by Christ showing the way we work. Whosoever worketh evil things, in the night he worketh, not in the dawn; according to the Apostle, saying, "They that are drunken, in the night are drunken; and they that sleep, in the night do sleep; let us that are of the day, be sober." He exhorteth us that after the day we should walk honestly: "As in the day, honestly let us walk." And again, "Ye," he saith, "are sons of light, and sons of day; we are not of night nor of darkness." Who are sons of night, and sons of darkness? They that work all evil things. To such a degree they are sons of night, that they fear lest the things which they work should be seen. ...No one therefore in the dawn worketh, except him that in Christ worketh. But he that while at leisure is mindful of Christ, on the Same doth meditate in all his actions, and He is a helper to him in a good work, lest through his weakness he fail. "And in the covering of Thy wings I will exult." I am cheerful in good works, because over me is the covering of Thy wings. If thou protect me not, forasmuch as I am a chicken, the kite will seize me. For our Lord Himself saith in a certain place to that Jerusalem, a certain city, where He was crucified: "Jerusalem," He saith, "Jerusalem, how often I have willed to gather thy sons, as though a hen her chickens, and thou wouldest not." Little ones we are: therefore may God protect us under the shadow of His wings. What when we shall have grown greater? A good thing it is for us that even then He should protect us, so that under Him the greater, alway we be chickens. For alway He is greater, however much we may have grown. Let no one say, let Him protect me while I am a little one: as if sometime he would attain to such magnitude, as should be self-sufficient. Without the protection of God, nought thou art. Alway by Him let us desire to be protected: then alway in Him we shall have power to be great, if alway under Him little we be. "And in the covering of Thy wings I will exult."
