What does Paul mean when he says he is crucified with Christ and yet lives?

Les teaches from Galatians 2:20 that Paul’s statement is classic: he is crucified with Christ by identification with Christ’s death, yet he lives. The life Paul now lives in the flesh is lived by the faith—Les prefers the faithfulness—of the Son of God. Les explains this as the very function of the Gospel: Christ died for the sins of the world, was buried, and rose from the dead. When a person comes under that forgiveness, everything is forgiven—past, present, and future—so we will never come into God’s presence with sin on our back, because it has all been paid for. Les says this is beyond human comprehension but is believed because the Book teaches we are forgiven all trespasses, not by anything we have done but by what Christ accomplished on our behalf. That makes the Gospel simple and yet complex, beyond full understanding this side of glory.
