But what did Jude mean by exhorting readers “to contend for the faith”? It certainly was not a call to use physical force or violence. Jude was referring to a spiritual battle, one requiring spiritual weapons (2 Corinthians 10:3-5). Jude exhorted followers of Christ to contend for the truth. As his letter explained, deceptive men were creeping into the church and perverting Christian doctrine with heresies that denied the truth.
“For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace” (Isaiah 9:6, NIV).
