Ephesians 2:1. “And you hath He quickened, who were dead in trespasses and sins:”
Because Jesus gained the victory over sin and death, He can offer us that same victory. Remember that Paul is writing to believers in Ephesus, not to the unsaved.
In the beginning of this rich passage on sin and salvation, Paul tells us that Jesus has quickened them. That is, He has made them alive, given them new life, because before accepting Him as Savior, they were dead in their sinful behaviors.
So it is for all believers everywhere across the centuries who have come to Him in faith, believing. We are given life instead of death, because Jesus Christ has paid the penalty for our sin and won the eternal victory over death.
