How can we tell whether or not a person is a true minister of God? How can we tell whether or not a person is a true believer? This is the discussion of this passage. Remember: Jude was the brother of our Lord. At first, he did not believe in Jesus Christ. But some time after the resurrection of Christ, he gave his heart to the Lord and surrendered his life to preach the gospel. Here we see him sitting down and writing to the believers of the first century. Preacher's Outline and Sermon Bible - Commentary - 1 & 2 Peter; 1, 2 & 3 John; Jude.
