Matthew 26:53
Do you think that I cannot appeal to my Father, and he will at once send me more than twelve legions of angels? The reminder of the available but unused divine resource: twelve legions of angels (approximately 72,000) are available at a single request. The I cannot appeal communicates that Jesus is choosing not to invoke the power, not that the power is unavailable. The choice to go to the cross is a genuine choice, not a necessity imposed from outside.
