Excerpt from Grace Notes: Daily Readings with Philip Yancey (eBook).
Judas was not the first or the last person to betray Jesus, merely the most famous.
To [the Japanese Christian novelist Shusaku Endo], the most powerful message of Jesus was his unquenchable love even for — especially for — people who betrayed him. When Judas led a lynch mob into the garden, Jesus addressed him as “Friend.” The other disciples deserted him but still he loved them. His nation had him executed; yet while stretched out naked in the posture of ultimate disgrace, Jesus roused himself for the cry, “Father, forgive them.”
