Although He is an all powerful God, He allowed himself to be powerless for a time. He was betrayed by those who said they would never deny Him. Jesus was abused, beaten, mocked and with his clothes torn, body bloodied from the torture, His tormenters and onlookers pointed, mocked and ridiculed Him. He felt abandonment as he cried out on the cross asking " Lord, Lord, Why have you forsaken me". Yet, in His final throws of life, before His breath left his body when Jesus knew the work was accomplished He said "IT IS FINISHED".
That work on the cross, that sacrifice of His life was made for you. To defeat that stronghold Satan have over your life.. Jesus said - IT IS FINISHED
