God has called His people to be very different. In the Old Testament we see Him giving laws to Israel while frequently mentioning that these laws are to set them apart from the other nations (Leviticus 20:25-26; Deuteronomy 7:5-6). They were different because God was with them. In the New Testament it is much the same. While we no longer have ceremonial laws, God still has standards for our behavior that set us apart as His different people (John 13:35, 15:17-19; 1 Peter 1:13-16, 2:9-10).
When you surrender to God, you are also surrendering to the call to be a very strange person. You won’t look like the world because you’ll have Jesus within you. When you work with Him, you’ll look more and more like Him every day. Which means you’ll be more and more unlike everyone else. Which will be quite obvious to everyone else.
When it’s obvious that you’re different and that you “ain’t from ’round here,” people will ask you questions. That’s when you get to tell them what God wants them to know. Have a ready answer (1 Peter 3:14-17), and tell them whatever God tells you to say. Answer their questions. It’s okay if you don’t know all the answers, just ask to get back to them. You can both learn together.
You’re weird. But that’s good. Because this is exactly who God called you to be.
