Webster's Collegiate 10th edition dictionary defines alien as, "...belonging or relating to another person, place or thing; otherworldly; differing in nature or character, typically to the point of incompatibility; a resident of another home, country or planet." Incompatibility: that word has had familiar meaning among Christians for centuries. In actuality, experiencing a feeling of "incompatibility" with this world is completely normal for Christians. Christians are called by Christ to be aliens in this world. They are redeemed, blood-bought, children of the living God and this automatically makes them different (but not better) than the rest of the world. In fact, in most cases, they are the outcasts. In Philippians 3:20-21, Paul writes, "But we [Christians] are citizens of Heaven, where the Lord Jesus Christ lives, and we are eagerly awaiting for Him to return as our Savior." Their citizenship is not of this Earth, it is awaiting them in the realms of Heaven. This is one of the biggest reasons we are aliens here, travelers, sojourners. It is also why the world looks at us as total weirdoes: we are waiting on Christ's return; an event the world does not believe is ever going to happen. In 1 Peter 2:11 we are given a warning: "Dear friends, I warn you, as temporary residents and foreigners, to keep away from worldly desires that wage war against your very souls." (emphasis added). The New International Version literally uses the word "alien" here. The text is essentially referring to us again as travelers. Peter is warning us to, first, not regard this Earth as our home. Secondly, we should not seek to acquire permanent possessions, wealth, or material items while on Earth. In addition, we should not form any attachments or arrangements that will impede our journey. Keep in mind that our daily walk with Christ is part of that journey. Do not attach yourself to anything that may hinder that. Lastly, we should constantly dwell on Heaven, our true, eternal home. ARE YOU AN ALIEN OR EARTHLING? .
