Joseph was imprisoned because of false accusations made by Potiphar's wife. He had at least two cell mates, a cupbearer and a baker—we do not know the charges against either prisoner.
Joseph's cell mates had dreams. By God's power, he interpreted the dreams, including which day the dream prophecies would be fulfilled. On Pharoah's birthday, two divinely inspired prophecies were fulfilled. The baker lost his life and the cupbearer was restored to his original position, perfectly fulfilling what God prophesied. Because of this dramatic display of divine interpretation the cupbearer remembered Joseph later.
This fulfillment of prophecy led directly to Joseph later being used to preserve the lineage of Jesus.
Is this birthday of Pharoah—and even the death of the cupbearer—supposed to be a negative event, even though God prophesied both the date and the events that would occur? If so, how?
It seems to me that you might as well say God disapproves of valuables of any kind because Achan's whole family was killed when he hid treasure from a city devoted to destruction. Or that God disapproves of giving addresses in front of audiences on the evidence of Herod's last performance.
Please explain why this account is contextually explained in such a positive light in My Book of Bible Stories and in such a negative light in specific reference to birthday celebrations.
