Mark 10:39
We can, they answered. Jesus said to them, you will drink the cup I drink and be baptized with the baptism I am baptized with — the confident we can is correct in outcome though not yet in understanding. Jesus confirms: you will. The church's tradition records that James was the first apostle martyred (Acts 12:2) and John lived through extreme suffering and exile. Their future suffering will be their participation in what they glibly claim they can endure.
