James and John had great zeal, but initially lacked eloquence and wisdom. Similarly, we need God to redirect our efforts to His purpose rather than our own.
In Mark 3:16-19, Jesus calls the disciples. He gives the brothers James and John a nickname, or title, "Boanerges," which is Greek for "Sons of Thunder."
James and John do not appear to have been selfish, but men of action ready to meet a challenge.
Herod Antipas, son of Herod the Great, played a significant role in the ministries of John the Baptist and Jesus Christ.
John presents Jesus, not as a phantom emanation, but as the reality, transcending the shadows represented by the temporal physical life.
John and James were related, but still had to have the Messiah revealed to them. God is involved in the details of our lives as well as the great events in history.
John emphasizes the reality of Jesus as the Logos (a word revealing hidden thought), the manifestation of God in the flesh, emphasizing His preexistence and divinity.
True greatness does not come from dominance but from serving with the attitude of a slave. Willingness to sacrifice self is the secret to success.
