João 10

17 "Because of this the Father loves me, in that I lay down my life so that I may take it up again. 18 No one takes it from me, but I lay it down of myself.*This is important! The cross did not kill Jesus; He dismissed His spirit—see John 19:30 and Matthew 27:50. In Mark 15:39 the loud shout followed immediately by death convinced the centurion. He had seen many crucifixions and was doubtless hardened to it. He knew that a person on a cross dies from asphyxiation. The weight of the body pushes the diaphragm against the lungs and you cannot breathe. Nailing the feet was a sadistic procedure that prolonged the agony—rather than die they would push against the nail to get a breath. Finally, when too weak to do that they would die for lack of air. (That is why they broke the legs of the two thieves; they then died within a few minutes.) Obviously, if you are dying without air you cannot shout! The centurion knew that the cross had not killed Jesus. But what mere human can just tell his spirit to leave? 2 + 2 = 4. Jesus had to be the Son of God. I have authority to lay it down, and I have authority to take it up again. This command I have received from my Father."*The whole procedure was part of the Plan. An ordinary human being can kill himself, all right, but cannot change his mind later and come back. To Jesus the Father gave the ability to reunite spirit and body—presumably a unique occurrence.
