“So you must live as God’s obedient children. Don’t slip back into your old ways of living to satisfy your own desires. You didn’t know any better then. But now you must be holy in everything you do, just as God who chose you is holy.”
The idea of being a citizen of Heaven, that God has granted you a citizenship in His holy land is not something we should take lightly. We have clear instruction as to how we should behave as Christ’s representatives.
