The KJV says this about JESUS's last act in mortality:
Jesus, when he had cried again with a loud voice, yielded up the ghost.
The JST adds a poignant and powerful statement from the Savior.
Jesus, when he had cried again with a loud voice,
saying, Father, it is finished, thy will is done,
yielded up the ghost.
Obviously much clearer. Definitely better.
You and the Holy Spirit be the judge. I feel that after suffering for numerous hours both on the cross and in the garden, JESUS would certainly have announced his victory over Sin, on His way to creating a victory over Death.
The statement that the Father's will (The Most High GOD) bookends beautifully with CHRIST's prayer for a way out in Gethsemane. There was no escape for JESUS if humanity was to be given an escape from Death and Satan and Hell.
I, for one, am literally eternally grateful that JESUS finished the hardest thing ever done. I am also thankful for a Bible that adds to the majesty of CHRIST.
