John 7:1-5
Early Disbelief of Jesus Brothers
1 After this, Jesus went around in Galilee, purposely staying away from Judea because the Jews there were waiting to take his life. 2 But when the Jewish Feast of Tabernacles was near, 3 Jesus' brothers said to him, "You ought to leave here and go to Judea, so that your disciples may see the miracles you do. 4 No one who wants to become a public figure acts in secret. Since you are doing these things, show yourself to the world." 5 For even his own brothers did not believe in him.
Jesus brothers (and sisters) in His early ministry, did not believe in Him...In fact, they ask Him why He don't go to Judea (leave town) to His disciples and let them see the miracles...It would have been interesting growing up with a Brother like Him...
What is even as interesting is that James and Jude, Jesus brothers would turn their disbelief in belief...St. Paul mentions in 1Corinthians 15:7 that then He (Jesus) appeared to James, then to all the apostles...St. Paul also, when he (St. Paul) is trying to learn about the resurrection and the life of Jesus, he (St. Paul) tells us in Galatians 1:18-24 that he went to Jerusalem to get acquainted with St. Peter and stayed with him for fifteen days... I saw no other apostles-only James, the Lord's brother...
So all the disciples and apostles make a sudden turn in their belief after the resurrection including, James...So even though St. James did not believe in the beginning, after living with Him for years, St. James would become a Christian leader in Israel...
This early period would be a period of change from the old traditional beliefs to a new belief system that would include Jesus and much suffering would happen...The Twelve with St. Peter and St. James, the apostles, and St. Paul would hold steadfast and witnessed the successful rise of Christianity...And because of their eyewitness to these things and their strong belief in Jesus, Christianity would grow quickly through a time of persecution...
