St. Luke 22:31-33

And the Lord said, Simon, Simon, behold, Satan hath desired to
sift you as wheat:
But I have prayed for thee, that thy faith fail not: and when 
thou art converted, strengthen thy brethren.

And he said unto him, Lord, I am ready to go with thee, both
into prison and to death.

St. Luke 22:40
And when he was at the place, he said unto them, Pray
that ye enter not into temptation....Saying, Father, if 
thou be willing, remove this cup from me: nevertheless 
not my will, but thine, be done.

And there appeared an angel unto him from heaven, 
strengthening him.

(Decided God's way was better than his way, and that
was the power of agreement that allowed him to be
strengthened from on High)
