The Lord promises to be our Father, to live among us — we who become His sons and daughters. He promises to make us His temples, to “live and move about among [us].” He promises that He will “be [our] God, and [we] shall be His people.” (2 Corinthians 6: 16, 17)
Because of these promises from God, Paul calls on us to “cleanse ourselves from all that can defile flesh or spirit, and in the fear of God complete our consecration.”
“For the gracious gifts of God and His calling are irrevocable. Just as formerly [we] were disobedient to God, but now receive mercy in the time of their disobedience, so now, when [we] receive mercy, they are proved disobedient, but only in order that they too may receive mercy. For in making all mankind prisoners to disobedience, God’s purpose is to show mercy to all mankind.” (Romans 11: 29 – 32)
Paul is telling us that all — both Jew and Gentile — are sinful, all alike are condemned and must be saved by God’s grace, by His lovingkindness and mercy.
“Therefore, my brothers,” writes Paul, “I implore you to by God’s mercy to offer your very selves to Him: a living sacrifice, dedicated and fit for His acceptance, the worship offered by mind and heart. Adapt yourselves no longer to the pattern of this present world, but let your minds be remade and your whole nature thus transformed.” (Romans 12: 1 – 2)
