2 Corinthians 4:12

So then death worketh in us, but life in you. [The apostle has been speaking of having and holding the knowledge of God in a mortal body. But the knowledge of God brings with it the eternal life that is within God, so that to have divine knowledge is to have divine life (1 John 1:3; 1 John 5:19). The knowledge of 2 Corinthians 4:6; therefore, gives place in this passage to the life which it produces. The minister of Christ, having in him the life of Christ (Galatians 2:20), becomes in a large measure a reduplication of the life and experiences of Christ. He is, as it were, constantly dying and being resurrected. With Paul death was a matter of daily experience (1 Corinthians 15:31). But by thus constantly dying and yet continuing to live, Paul typically re-enacted the crucifixion and resurrection of the Lord. By surviving so many trials he made it evident to the world that he was sustained by a life other than human, viz.: the life of Jesus. Moreover, the daily sacrifice of the life of Paul, like the sacrifice of Christ, worked out life and blessing for others, notably the Corinthians, to whom he wrote.]
