Oh boy, Peter is at it again! He somehow (First Peter 2 verses 11 and 12) says in effect, "People are watching Y O U and because of that, they need to see you as different." It's interesting here how he points out (to the people to whom he writes) that they are not living where they used to live, so the people have only heard rumors about how "believers" act, and what they do.
In other words, they have heard everything on the grapevine (radio and TV today) about how bad people like "that" are, and fully expect you to be just like "that." His answer is "be different." Don't let your behavior confirm what they have heard about hypocrites, shysters, murderers, thieves or adulterers. Peter's challange is "be better than that – in fact be excellent in how you live." (kinda hard just being normal, let alone reach for "excellent")
Tough call to action. Let them see something better in me? It's like he is asking me to be so good (the way I act, talk, treat people) that they see a difference. Now that's worth praying about every day, because every day is new and there are the people from yesterday who will see me again, and people who have never seeen or heard me before.
Ask yourself, "what impact will I have today?"
