Biblical Concept: Stop Acting Like An Unbeliever

 When a human believes in Christ for eternal life, they become a new spiritual creation (2 Corinthians 5:17).  However, the human retains their sin nature (Romans 7:14-25).  Thus, the following Biblical texts  encourage and command to stop following that nature to sin which dwells in each human. Christians need to stop acting like the unbelievers that they once were - Ephesians 4:17-5:17, Colossians 3:5-10, Romans 6:1-14, and 1 Peter 4:1-5.
