1 So conscious are you of the affection which exists between us that you cannot but recognize the love and passion with which I strove to prolong our common sojourn in the desert. This very letter— blotted, as you see, with tears— gives evidence of the lamentation and weeping with which I accompanied your departure. With the pretty ways of a child you then softened your refusal by soothing words, and I, being off my guard, knew not what to do. Was I to hold my peace?
I could not conceal my eagerness by a show of indifference. Or was I to entreat you yet more earnestly? You would have refused to listen, for your love was not like mine. Despised affection has taken the one course open to it. Unable to keep you when present, it goes in search of you when absent. You asked me yourself, when you were going away, to invite you to the desert when I took up my quarters there, and I for my part promised to do so. Accordingly I invite you now; come, and come quickly.
Do not call to mind old ties; the desert is for those who have left all. Nor let the hardships of our former travels deter you. You believe in Christ, believe also in His words: “Seek ye first the kingdom of God and all these things shall be added unto you.” Take neither scrip nor staff. He is rich enough who is poor— with Christ.
