2 Corinthians 4:11

Paul faced threats to his life daily for his witness to Jesus Christ (cf. 1 Corinthians 15:30-31). This seems clearly to be what he meant by "the dying of Jesus." There are three other ways that the New Testament associates us with Jesus’ death, but these are not in view here. They are our identification with His death in baptism (Romans 6:3-5), our daily mortification of the flesh (Galatians 5:24), and our physical debilitation as we serve Christ.

Paradoxically the death and the life of Jesus were simultaneously obvious in Paul’s experience (cf. 2 Corinthians 1:4-5). Though living, Paul was always in danger of dying because enemies of Jesus rejected him and tried to kill him. However even though his body was in the process of aging and dying God kept giving him life, as He provided resurrection life to Jesus, so Paul could continue to serve Him.
