Jesus's cup was defined in Gethsemane as the innocent suffering unto death that was reserved from eternity. It's often unnoted that Jesus said in Matthew, if there is no other way for the cup to pass except that he drink it, God's will be done. His prayer was answered and the cup passed, but the only way was for all punishment to be drained to the dregs. Jesus's baptism was not just the mystic trinity of water, blood, and spirit, present at his birth and his death and symbolized in Christian sacrament; it was a baptism of fire he had yet to undergo. And this can be rephrased as an enshrouding in light. Just as his destiny was to return humanity to being creatures of light, so he tells Boanerges that we too will be creatures of light. Which is the same that Daniel said, the righteous will shine like the stars forever, not just a clever metaphor. Hidden truths.
