In modern fiction, we have the popular idea of a zombie.
Someone that was alive and has died, that is now existing in an animated state that mimics life, but is now ruled entirely by appetite or the command of another (in the case of voodoo zombies).
This, however, is exactly the OPPOSITE of what happens to a Christian. A person who was dead in their sins (Col 2:13 & Eph 2:1), ruled by their flesh, controlled by their sin nature, and under the influence of Satan (Eph 2:2-3), suddenly becomes alive in Christ! (Eph 2:4-10)
In the Book of John, chapter 10, verse 10, Jesus said that He came so that we may HAVE life (which means that you don't have life without Him) and have life more abundantly!
The "life" that the world touts and promotes is just a pale shadow of true life! Those around us are the true zombies, dead but thinking they are alive. Rotting and decaying, but believing that they can find happiness and satisfaction in sating their appetites.
Share HIM. Not church. Not "god". Not "spiritual enlightenment". Share JESUS.
