Charles H. Spurgeon on Psalms 22:1

"My God, my God." The repetition is expressive of fervent desire —"My God," in an especial sense, as in his words after the resurrection to Mary Magdalene, "I ascend unto my God, and your God;" "My God," not as the Son of God only, but in that nature which he hath assumed, as the beloved Son in whom the Father is well pleased; who is loved of the Father and who loveth the Father more than the whole universe. It is observed that this expression, "My God," is three times repeated. Dionysius, quoted by Isaac Williams.
