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.
Romans 8:11 ESV

The flesh is sanctified by a reborn spirit in spite of its continued inclination toward death, and the resurrection of Yeshua is a demonstration that God is able to raise us too and will do so at the final judgment.

“His spirit dwelling in you” is the same as “the Spirit of him who raised Jesus”. This is the indwelling of the Holy Spirit in the individual believer.
