1 Peter 2:11-12
"Dear friends, I urge you as aliens and strangers in the world, to abstain from sinful desires, which war against your soul. Live such good lives among the pagans that, though they accuse you of doing wrong, they may see your good deeds and glorify God on the day he visits us."
People should know that there is something different about you. I think that the easiest way for people to notice that is through radiating God's love for other people through our daily actions. It's about putting yourself last. It's about putting the opinions of others above your own. It's about the little things that we (as Christians) will do for one another that no one else would do.
Let me know if you have any stories of how you have put others first in the comment section below!
