Alien
Though the Bible talks about aliens, even commanding kindness toward them, the world doesn't imply creatures from other planets. An alien is anyone who is a stranger to your town or country.

The Bible also calls us aliens. Believing in Jesus Christ and following his teachings means having different goals and motives than the people around us. Don't worry about being different. Follow Jesus; let him worry about what others think of you.

The ancient Hebrews were often outsiders in foreign lands.
Genesis 15:13; 23:4
Exodus 6:4; 23:9
Be kind to those who are strangers. Doing so is like being kind to God himself.
Exodus 22:21
Leviticus 19:9-10
Deuteronomy 14:28-29
Jeremiah 17:5-7
Matthew 25:35-44
Being Christians puts us at odds with the world; we're "aliens."

1 Peter 2:11
