In the 2007 film, I Am Legend, Robert Neville (played by Will Smith) is one of the few immune survivors of a pandemic that turns the diseased into human-hunting zombies. Neville is also a virologist, and though other survivors fled to find safety elsewhere, Neville remained in New York City attempting to develop a cure for the deadly disease.
His self-appointed mission involves capturing diseased zombies, and using them as test subjects for experimental vaccines he develops from his own blood. He believes that since he is immune, then his blood must carry the key to a cure. You can watch the rest of the movie to find out what happens.
Neville’s dramatic (horrific) search for a cure is based (loosely) on reality. Pathologists do take blood samples from individuals who are immune to various diseases to try and isolate the antibodies that fight those diseases. For example, in 2009, an article in Science reported some progress in the area of HIV-fighting antibodies. But, no doctor will find a cure for the deadliest disease of all: Death.
And yet, an average thirty-something from a Podunk town in the middle of nowhere, and not a doctor, but the son of a poor carpenter, gets Himself nailed to a Roman cross, dies, is buried, and rises from the dead three days later. He faced the disease that kills every man, woman, plant and animal, and was found to be immune.
In other words, the cure for Death is in His blood.
Just think how ridiculous and incredible that sounds. Jesus was dead, for three days, and He came back to life. And, He never died again. So, now He can bring you back from the dead, too.
But, that’s just exactly what the Bible says about Jesus:
Romans 6:4-5 (ESV)
We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. 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.
This leads us to another good “nutshell” definition of the Gospel: Jesus Christ.
