Create in me a clean heart, O God, and put a new and right spirit within me. Do not cast me away from your presence, and do not take your holy spirit from me. Restore to me the joy of your salvation, and sustain in me a willing spirit. (Psalm 51:10-12)

But Jesus said to them, “You do not know what you are asking. Are you able to drink the cup that I drink, or be baptized with the baptism that I am baptized with?” They replied, “We are able.” Then Jesus said to them, “The cup that I drink you will drink; and with the baptism with which I am baptized, you will be baptized; but to sit at my right hand or at my left is not mine to grant, but it is for those for whom it has been prepared.”

Mark 10:38-40
