The people of God in Scripture are, persistently, a people in motion. Abraham was called to leave "his country, and his kindred, and his father's house" with no specific destination named — "a land that I will shew thee." God gave him direction without a map. The call to leave is part of the narrative of faith from the very beginning. Being uprooted is not the exception in the biblical story. It is one of its central threads.
The word the New Testament uses for a Christian resident is paroikos — a stranger, a temporary resident, someone living in a place that is not their permanent home. Peter writes to "strangers and pilgrims" not as a metaphor for detachment from the world but as a description of a fundamental reality: those who follow Christ have a citizenship elsewhere. Every earthly address is, in a sense, temporary. This doesn't make the grief of leaving less real. It gives that grief a larger frame.
Ruth's commitment to Naomi in Ruth 1:16 — "whither thou goest, I will go" — is set against a background of devastating loss and displacement. Ruth was leaving her own country to follow her mother-in-law into a foreign land. What sustained her wasn't certainty about the destination. It was a covenant loyalty to the person she was traveling with. For Christians, moving is always into the presence of the same God — the one who said "I will never leave thee, nor forsake thee."
