Actualy SC, that was a briliant observation. The disciples wanted all the icecream, and prizes, and none of the hard work ---impossible for humans actualy. So "Cup" refences such as "Are You able to drink from My cup" would be no --because none of us are worthy like the Lamb.
However, in our weaknessess, we make God strong, because God shows the world, when we must drink of the bitter cup of chastisements when we sin against God, after being saved, ----just how much more strong God has to be for us ----to cary us thru.
1) And like Job, who was a Type for Christ ---as the Servant, who was righteous in all His ways, and did not deserve His sufferings,
2) Job was also a type for us, for when we become perfect, thru the "Imparted" grace of God, and "imparted" glory of God within us, as saved ---that when we do doubt { as Job did doubt } then when we are weak, God has to cary us ---because God did have to "correct" Job,
3) And after all of Job's suffering, and God setting him straight, what did God require of Job: Don't forgett to pray for your friends ---who job knew to be no freinds of his, on how they blamed him ----and yet he was to forgive them, and pray for them just the same!!!!!!!!!!!!!!!
4) And when we are like our master, like Christ, as his ambasadors, then do we not ask for our bitter cup to pass from us. God answered Christ and us both, when there are times God has to say "No" your bitter cup will not pass ---But it is because I love more than Just You, My Son(s) ---with us being sons and daughters by adoption into God's family
