Romans 6:5-9

For if we have been united with him in a death like his, we will certainly also be united with him in a resurrection like his. For we know that our old self was crucified with him so that the body ruled by sin might be done away with, that we should no longer be slaves to sin— because anyone who has died has been set free from sin.
Now if we died with Christ, we believe that we will also live with him. For we know that since Christ was raised from the dead, he cannot die again; death no longer has mastery over him.
