Jesus’ young childhood was likely very similar to every other child in Nazareth. He was cared for by loving parents who fed and clothed him, nurtured and adored him and brought him up in the traditional Jewish ways, exposing him to the Temple and teachings of God. He lived in a home surrounded by half-siblings. Jesus was born in Bethlehem, in a stable, during a tax audit but raised in his home town of Nazareth, where it was often said, “Nothing good could come from there.”
Jesus grew strong in Spirit, was filled with the Holy Spirit, filled with wisdom; and the grace of God was upon Him (NKJV). At 12 years old Jesus accompanied his family to the Temple to celebrate the Passover. It was there that he was found engaging the Rabbi’s in discussion of the Holy Scriptures. It was also at this time, that Jesus acknowledged God’s calling on His life and His unique relationship to God the Father. Here too, scripture gives us a glimpse into the minds of Joseph and Mary.
As seen by their reaction to the Passover incident, Mary and Joseph seemed to have lost sight of Jesus’ calling. I believe this event set the stage for two important issues, revealed to us through scripture. First, Jesus was not received by his own, Dr. Luke tells us in 4:24. He was scorned by his neighbors in his familiar town of Nazareth. In Luke 4:16-21 we are told the story of how Jesus stood up in the Synagogue on the Sabbath and read from the scriptures, ending with, “Today this scripture is fulfilled within your hearing.” His leadership had officially begun
It is noteworthy to point out that Jesus leadership style throughout his training and ministry preparation was that of a servant. Jesus called each disciple specifically, knowing what it would mean to each one. Each was an ordinary man but called to sacrifice, hardship, rejection and death. He taught them to preserver in prayer, humble themselves, and to withdraw to rest and fellowship. Jesus led them, fed them and healed them. He brought them a fresh message and taught them through parables. It was by modeling this type of leadership style that he later was able to mentor and teach His followers how to teach and preach after He was gone.
John the Beloved, Jesus and James were related. Jesus and James, were half-brothers and John, son of Zebedee was a first cousin to Jesus and James because Salome, the mother of John was Mary’s sister. They all lived in a relatively small geographic area and likely shared similar if not identical upbringing. They all studied under the local rabbi, and worked in the family business under their fathers. What differed among the three were their personalities. John the Beloved was spirited, ambitious, zealous for truth and passionate.
James was a sibling to Jesus. He did not believe Jesus was more than that and certainly not the Messiah. John 7:3-5 tells us that he, along with his brothers, mocked Jesus, taunting him to go public if he was truly the Messiah and perform miracles.
Clearly, James was not a fan of His brother’s ministry. Unfortunately, this undoubtedly created a wedge between the two, although only on the side of James, since we know that Jesus did not sin. It was not until after the crucifixion that James became a believer in Christ. “What changed his mind? the resurrection. Regardless of his doubt and rejection for the Christ, he became a strong leader for the church in Jerusalem. 
James likely carried a burden until his death as a martyr, regretting that he had not believed in the deity of his brother. Although forgiven, that particular offense would have been a tough burden to lay at the foot of the cross.
John is described as having a temper and was quick to act. He also had a spiritual side that early on drove him to follow John the Baptist, which is the setting in which we see John beginning to see Jesus as the Messiah and following Him. John had to learn to balance his passionate zeal for truth, with love.
All the disciples were mentored and taught by Jesus and absorbed everything the Master had to say. John observed, listened and learned to love Jesus and to preach as Jesus did. John was transformed into spiritual maturity through his tutelage under Christ. He learned a balance between the hard edge of truth and the softer side of love.
Even after the resurrection Jesus continued to teach, as evident from Paul’s experience on the road to Damascus. It was there that Paul’s leadership style changed. He became a servant of the Lord Jesus and a leader of people to the cross.
Jesus had a unique and poignant curriculum that reached His followers where they were and changed them into ‘torchbearers for the Gospel’.
