I just finished reading Beginning at Moses by Michael P.V. Barrett several weeks ago. It's about finding Christ in the Old Testament. Mr. Barrett is talking about Psalm 22 on page 312.
The Lord expresses His confidence that His prayers have been heard and then in the next section begins to detail the answer to those prayers. It becomes clear in the second division that all the suffering of the first division was not in vain. As you meditate your way through this Psalm, do so with what should become an overwhelming impression that you are reading what the blessed Savior said, thought, and prayed while He was suffering vicariously for His people on the cross. The New Testament reveals that the initial lament was audible: 'My God, my God, why has thou forsaken me?' (see Matthew 27:46; Mark 15:34). There is no indication that men could hear the rest of the prayer, but God heard. In this Psalm, we are allowed into the mind and soul of the Savior. You can see why I say that this is holy ground.
The first division highlights three spheres of suffering endured by the Savior. He suffered before the holy God (1-5), by cruel men (6-11), and in His whole person, body and soul (12-18) The opening stanza brings us to the heart of the atonement. The simple answer to Christ's agonizing question 'Why has thou forsaken me?' is that God forsook His Son in order that He might forgive us. With our sin and guilt imputed to Him, He who knew no sin, having become sin for us, took the full force of God's just and necessary wrath against our sin. While Christ was suffering on the cross, God dealt with Him in terms of us. I confess a total inability to explain the utter dereliction of Christ that is expressed by this statement. It boggles the mind. It declares how absolutely offensive sin is to the holiness of God and how absolutely gracious God is in giving His dear Son to be the only Savior. How dare any man say that there is any other way to God!
Well, it would be silly of me to try to add anything to that.
