"The Book of Psalms is the diary of Jesus Christ,
written in advance of His becoming a man.
When Jesus met with His disciples after the resurrection, He explained the Old Testament Scriptures to them. He studied specifically the psalms concerning His sufferings, death and resurrection. Earlier in His ministry He stated that the Old Testament testified of Him.
The Old Testament is to be studied in the light of the life of Christ. If one refuses to believe that the Old Testament testifies of Christ, then he cannot believe the New Testament.
Psalm 22 shows Christ living by faith from His birth.
“You are He who took Me out of the womb; You made Me trust when I was on My mother’s breasts. I was cast upon You from birth. From My mother’s womb You have been My God” (verses 9, 10).
From the time of His birth until He died, Christ lived by faith in the power of God’s keeping care. Just as we learn by faith so did Christ learn by faith.
When Christ was on the cross, He spoke what are known as the seven last words.
*The first three concern Christ’s relationship with others,
*the last four are about His union with His heavenly Father.
The last four sayings of Christ came directly from the Psalms. Unlike the first three, these four are not concerned about others.
Christ was now entering into His time of extreme agony, as He began to feel the separation between Himself and His Father. We read in Psalm 22:1, “My God, My God, why have You forsaken Me?” The New Testament presents it as, “Eloi, eloi, lama
Later Christ said, “I thirst” (John 19:28). This is based on Psalm 69:21, which states that He would be given gall for food and vinegar to drink.
The next statement of Jesus is recorded in John 19:30 where He says, “It is finished!” This is from Psalm 22:31, meaning that He has done or accomplished the work He was sent to do.
In Psalm 22 we observe the agony of separation that occurred between Christ and His heavenly Father. Then He died with these words on His lips, “Father, ‘into Your hands I commend My spirit’” (Luke 23:46), a quotation from Psalm 31:5.
During the entire closing hours on the cross,
Christ quoted from the Psalms.
He must have lived by the Psalms, and then died by them."ChristInThePsalms by GeraldFinnman
