"There are many negative things that can be said about James and John," writes William Barclay. "They were nakedly ambitious and proud: they wanted, and believed they deserved, places of honor in Jesus' kingdom. They were ignorant and insensitive: their request for places of honor came right after Jesus had told of His coming suffering and death. But there's one positive thing you can say about James and John: they believed in Jesus. Here was a poor, homeless, persecuted carpenter and yet James and John believed Jesus was a king. They believed that He would conquer the power structure of Rome." Even their crude ambition reflected their faith in Christ.
