When Peter addresses the persecuted church in Asia Minor, He emphasizes setting one's hope on the second coming of Christ. In this, Peter quotes a command that occurs five times in the Old Testament book of Leviticus, where it says "Be Holy because I am holy." What does holiness mean, especially in today's world? Only with Christ can you stop conforming to evil desires that you constantly gave into when you were disobedient. Only with Christ can you be different from this world, and subdue your selfish nature. It is when you trust Christ to help you live holy, you can be most sober-minded (i.e. alert) and set your hope on Him. It is only with this His help one can live holy (and in a peaceable state of mind) in an immoral society that is consistently breaking down and causing panic, unease, instability, and anxiety.
