Mark 3:18 lists among Jesus’ 12 disciples “Andrew, and Philip, and Bartholomew, and Matthew, and Thomas, and James the son of Alphaeus, and Thaddaeus, and Simon the Zealot.”
Matthew was a former tax collector for the Roman Empire, while Warren Wiersbe notes that “The Zealots were a group of Jewish extremists organized to overthrow Rome, and they used every means available to advance their cause. The historian Josephus called them ‘daggermen.’ It would be interesting to know how Simon the Zealot responded when he first met Matthew, a former employee of Rome.” They learned to prioritize following Jesus, but I suspect it took some time and patience on Jesus’ part.
No enemy of God is beyond His grace, and no enemy of yours is beyond His grace either!
