How does Paul live after being crucified with Christ?

Les explains that Paul's statement in Galatians 2:20 follows the Gospel fact that Christ died for the sins of the world, was buried, and rose from the dead. Because Christ paid for sin, believers are forgiven everything—past, present, and future—and will never come into God's presence with sin on their back. Paul says that even though he is crucified by identification with Christ's death, yet he lives, and the life he now lives in the flesh is lived by faith. Les prefers to call it the faithfulness of the Son of God. This is beyond human comprehension, but it is believed because that is what the Book teaches.
