In a technical article on the Greek word for â€œfalse teacherâ€ used in 2 Peter 2:1, K. Rengstorf says this term shows their teaching was false and â€œin every respect they are a perversion of the Christian Î´Î¹Î´Î±ÏƒÎºÎ¿Î»Î¿Ï‚ [teacher], since they reject the claim of Jesus to domination over their whole lives.â€
This is an accurate description of Peterâ€™s point since he stresses that these people do not live according to the teachings of Christ.Â What struck me in the article was the use of the word â€œdomination.â€ If we resist Jesusâ€™ domination of our lives we will be false teachers. He must rule all. Rebels will not be able to proclaim the Kingdom of God and the Lordship of Christ.
