What does the Bible say about drinking from the cup of Christ?

In Mark 10:38, Jesus asks James and John if they can drink from the cup He drinks from, which represents the profound suffering and divine wrath He was about to endure for the sins of His people. This cup is linked to the agony of Gethsemane, where Jesus prayed about the possibility of it passing from Him. This illustrates that drinking from the cup is not merely about physical suffering but includes being made sin for His people, a theme seen throughout the New Testament. The disciples, unaware of the full implications, confidently claim they can, revealing both their misunderstanding and the depth of Christ's atoning work.
