In Paul's view, "Jesus' death was not a defeat but was for the believers' benefit," a sacrifice which substitutes for the lives of others, and frees them from the bondage of sin. Believers participate in Christ's death and resurrection by their baptism. The resurrection of Jesus was of primary importance to Paul, bringing the promise of salvation to believers. Paul taught that, when Christ returned, those who had died believing in Christ as the saviour of mankind would be brought back to life, while those still alive would be "caught up in the clouds together with them to meet the Lord in the air"
