And if anyone does not have the Spirit of Christ, they do not belong to Christ. ¹⁰ But if Christ is in you, then even though your body is subject to death because of sin, the Spirit gives life because of righteousness. ¹¹ And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies because of his Spirit who lives in you.
