We are just beginning the study of this book in the bible.
Jude is a severe warning of
-who we are
-who we aught to be
-who we should believe
Jude was a servant of Jesus. He was the brother of James (not Judas of Oscariot). Jude, Judas, Judiah were very popular Roman names in the time of the Roman empire.
Jude was the half brother of Jesus. He initially did not believe Jesus was the son of God whose's mission was to come to earth to save everyone from sin. He became a believer and a leader in the early Christian church. Acts 1:13, Mathew 13:44
Jude served with Peter and Paul. He was very concerned about false prophets and apostosee in the church. Check out these bible links to explore more of what Jude wrote about:
