"Cup" in the Bible: Matthew 26:39
In the hours before his trial, Jesus prays to God to life his "cup"--that is, the suffering that have been laid out for him. Jesus does not hesitate to ask God to spare him from suffering, but he is willing to accept God's will regardless.
Your will - a Christian perspective
As his death neared, Jesus prayed that his fate might be averted--but even in doing so, he humbly submitted himself to God. He asked that God's will be done, even if it meant horrible suffering for Jesus.
