Dear friends, I warn you as “temporary residents and foreigners” to keep away from worldly desires that wage war against your very souls. Be careful to live properly among your unbelieving neighbors. Then even if t hey accuse you of doing wrong, they will see your honorable behavior, and they will give honor to God when he judges the world. 1 Peter 2:11-12
For those who are Christians, know that you are not saved just for yourself. There is no "it's just me and Jesus" in Christ. Part of fulfilling the commandment to love is to reach out to others. With that being true, make sure you live a holy life and always be genuine. It's not just to honor God, though that is the greatest reason. But it's so that people who don't know Jesus can realize that His love is real. After all, we have only ourselves to blame if people don't come to know Christ and His goodness because they don't trust us.
