John 3:7-8
"...'You[d] must be born again.’ 8 The wind[e] blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.”

We aren't going to fit in here if we're truly born again. The world won't be able to figure us out! A man I respect very much once told a story (I don't remember if it's true, but it's certainly stuck with me!). He said that once their was a country that was stricken with poverty. The Christians of that country and the neighboring one got together and started a feeding system. The ruler was shocked by their actions and said, "They're not only feeding their own, but ours too! I hate them! They must go - it's my responsibility to do that!" (Paraphrased =P). So the citizens had no clue where the Christians had come from or where they had gone, but they had made such an impact on the citizens' lives that the country eventually pulled itself out of debt and poverty. That's our job - be so loving that we impact this world just by living.
