At that time Jesus’ own brothers​—James, Joseph, Simon, and Judas—​did not believe that Jesus was God’s Son. They must not have believed what the angel Gabriel had told their mother. (Luke 1:30-33)

Were Jesus’ brothers also his disciples?— The Bible says that at first they were “not exercising faith in him.” (John 7:5) Later, however, James and Judas (also called Jude) became his disciples, and they even wrote books of the Bible. Do you know which books they wrote?— Yes, James and Jude.

Although Jesus’ sisters are not named in the Bible, we know that he had at least two. However, there could have been more. Did these sisters become his followers?— The Bible doesn’t say, so we don’t know.
