So then death worketh in us, but life in you.
The "death" of Christ, manifested in the continual 'perishing of our outward man' (2 Corinthians 4:16), works in us, and is the means of working spiritual "life" in you. The life whereof we witness (note, 2 Corinthians 4:11; 2 Corinthians 1:6-7) in our dying flesh extends beyond ourselves, by our very dying, to you.
