Nomadic: living the life of a nomad.
Peter referred to believers as "foreigners and exiles" in 1 Peter 2:11 and indeed we are a nomadic people who travel from place to place but whose permanent dwelling is not to be found until we arrive in our eternal home.
For here we have no lasting city, but we seek the city that is to come. (Hebrews 13:14)
Jesus said that He is "preparing a place for us" (John 14:1-3) and that we should not be troubled about the future. Instead, we should seek after Him and the things associated with His kingdom.
But our citizenship is in heaven, and from it we await a Savior, the Lord Jesus Christ. (Philippians 3:20)
As Christians, we live in an evil and corrupt world. We were all well acquainted with this world's culture at one time but now have become strangers, foreigners and aliens to it. We are in God's family and God's household and we anxiously wait for the day when we will walk the streets of God with Him.
You may not own a really cool Nomad (or a 1956 Chevrolet station wagon like the one pictured), but you can live the holy and godly life of one. And while you're at it, look around for where God is stirring the waters and catch the wave!
