“For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his” (Romans 6:5). “If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you” (Romans 8:11). “If we have died with him, we will also live with him” (2 Timothy 2:11).
The keys of death were hung on the inside of Christ’s tomb. From the outside, Christ could do many wonderful works, including raising a twelve-year-old girl and two men from the dead—only to die again (Mark 5:41-42; Luke 7:14-15; John 11:43-44). If any were to be raised from the dead, never to die again, Christ would have to die for them, enter the tomb, take the keys, and unlock the door of death from the inside. The resurrection of Jesus is God’s gift and proof that his death was completely successful in blotting out the sins of his people and removing the wrath of God. You can see this in the word “therefore.” Christ was “obedient to the point of death, even death on a cross. Therefore God has highly exalted
him” (Philippians 2:8-9). From the cross the Son of God cried, “It is finished” (John 19:30). And by means of the resurrection, God the Father cries, “It was finished indeed!” The great work of paying for our sin and providing our righteousness and satisfying God’s justice was finished in the death of Jesus.
