Jesus asserted that no one was taking His life from Him, but that He would lay it down for the sheep, and that He would take it up again. Paul affirmed that Jesus gave Himself up for us. Although this is all language which fits with the language of sacrifice, events surrounding the crucifixion indicate that Jesus willingly yielded up His Spirit. No one took His life. And He endured all of this freely and willingly so that you and I could have life eternal. Amazing love!
