For this reason I bow my knees to the Father of our Lord Jesus Christ, from whom the whole family in heaven and earth is named, that He would grant you, according to the riches of His glory, to be strengthened with might through His Spirit in the inner man, that Christ may dwell in your hearts through faith; that you, being rooted and grounded in love, may be able to comprehend with all the saints what is the width and length and depth and height—to know the love of Christ which passes knowledge; that you may be filled with all the fullness of God. (Eph 3:14–19)
Ho! You sinner, be of good cheer! You see where it is that there is joy at your return. What meaning for us have those themes of the Lord’s parables? Is not the fact that a woman has lost a drachma, and seeks it and finds it, and invites her female friends to share her joy, an example of a restored sinner? There strays, withal, one little ewe of the shepherd’s; but the flock was not more dear than the one: that one is earnestly sought; the one is longed for instead of all; and at length she is found, and is carried back on the shoulders of the shepherd himself; for much had she toiled in straying. That most gentle father, likewise, I will not pass over in silence, who calls his prodigal son home, and willingly receives him repentant after his indigence, slays his best fattened calf, and graces his joy with a banquet. Why not? He had found the son whom he had lost; he had felt him to be all the dearer of whom he had made a gain. Who is that father to be understood by us to be? God, surely: no one is so truly a Father; no one so rich in paternal love. He, then, will receive you, His own son, back, even if you have squandered what you had received from Him, even if you return naked—just because you have returned; and will joy more over your return than over the sobriety of the other; but only if you heartily repent—if you compare your own hunger with the plenty of your Father’s “hired servants”—if you leave behind you the swine, that unclean herd—if you again seek your Father, offended though He be, saying, “I have sinned, nor am worthy any longer to be called Yours.”
