One realization came to me as I research my talk for this Sunday about prayer. Prayer opened, and also closed, the proceeding of the Atonement on Earth:

“[Jesus] kneeled down, and prayed, saying, Father, if thou be willing, remove this cup from me; nevertheless not my will, by thine, be done. And there appeared an angel unto him from heaven, strengthening him. And being in agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground.”

- Luke 22:41-44

And it ends with a  prayer, just before Christ died:

“And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me?”

- Matthew 27:46
