Romans 8:10-11 But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness. (11) If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.
All human beings are dead men walking due to sin. Although physically alive, all human beings are born spiritually dead because of sin and will also die a physical death because of sin. However, IF the Spirit of God dwells in a person, that person has been given spiritual life. He is a new creation in Christ and although his physical body will suffer death, he has been raised to new life now and will be raised to life at the last day just as Jesus was raised to life. The New Covenant through the blood of Christ gives believers grace, the indwelling Spirit, and life.
