I concluded my lectures on Mark's Gospel yesterday without reaching the theme on prayer (what a shame!) where Jesus (only in Mark) said 3 times: all things are possible with God -
1) RSV Mark 9:23 And Jesus said to him, "If you can! All things are possible to him who believes."
2) RSV Mark 10:26 And they were exceedingly astonished, and said to him, "Then who can be saved?" 27 Jesus looked at them and said, "With men it is impossible, but not with God; for all things are possible with God."
3) RSV Mark 14:36 And he said, "Abba, Father, all things are possible to thee; remove this cup from me; yet not what I will, but what thou wilt."
