Jesus is the Messiah as the Scripture said

John 19:17-30
Jesus carried his own cross, went out to the place of the Skull- Golgotha. Other two crucified with Jesus.
Pilate had a notice prepared and fastened to the cross. It read" Jesus of Mazareth, The King of The Jews"
When the soldiers crucified Jesus they took his clothes, divided them into four shares. The garment was seamless, woven in one piece from top to bottom, They decided by lot who will get it." This happened that the scripture might be fulfilled as (Psalm 22:18).
Near the cross of Jesus stood his mother, his mother's sister, Mary the wife of Clopas, and Mary Magdalene. Four women were there.
Jesus said to his mother,"Dear woman, here is your son," and to the disciple, John, "Here is your mother.", From that time on, this disciple took her into his home.
Later, knowing that all was now completed and so that the Scripture would be fulfilled, Jesus said, "I am thirsty." A jar of wine vinegar was they, so they soaked a sponge in it, pt the sponge on a stalk of the hyssop plant, and lifted it to Jesus' lips. When Jesus received the drink, Jesus said,"It is finished." He bowed his head and gave up his spirit.
Why?
All of John described are shown Jesus did everything same as Scripture said. He is the Messiah.
Pilate admitted Jesus is the King of the Jews, it might mock Jesus, but it is declare the identity of Jesus is a king of the Jews.
Jesus asked John took care his mother.
Again John's account shows  vivid, eye-witness recollection of events- the detail of the inscription
How?
Jesus is the Messiah, He is the King of kings. Today is the day to memory Jesus suffered on the cross for our sin. Let meditate his love and the meaning of cross.
