Salvation is for God’s glory by putting on display His boundless mercy and love for those who are spiritually dead because of their sinfulness. Far more than anything else, a spiritually dead person needs to be made alive by God. Salvation brings spiritual life to the dead. Not only is the believer dead to sin and alive to righteousness through Christ’s resurrection, but he also enjoys his Lord’s exaltation and shares in His preeminent glory.
