'Reason' in the Bible

Both Jesus who sanctifies and those who are sanctified [that is, spiritually transformed, made holy, and set apart for God’s purpose] are all from one Father; for this reason He is not ashamed to call them brothers and sisters,

But the truth is that they were longing for a better country, that is, a heavenly one. For that reason God is not ashamed [of them or] to be called their God [even to be surnamed their God—the God of Abraham, Isaac, and Jacob]; for He has prepared a city for them.
