Peace,
i'm pretty late but...just wanted to add this:
the Apostles were not at the crucifixion. [Mark 14:50]
NO ONE is greater than God and no one can direct Him... but Jesus acknowledged someone greater than himself whose will was distinct from his own.
couldn't have said it better myself!! it should be noted that Jesus(peace and blessings be upon him) makes reference to the Father being his God.
Jesus said to her, "Stop clinging to Me, for I have not yet ascended to the Father; but go to My brethren and say to them, 'I ascend to My Father and your Father, and My God and your God.'" (John 20:17 NIV)
peace.
