Alice In Chains – Get Born Again lyrics

Seems like they're definitely saying there was no such thing as the physical resurrection (of Jesus Christ), that people believe in it due to a sad psychological need to be rescued from the wreckage of their life. Saddest line. "I pretend you're still alive" (!)
Christ is their "fair weather friend" who is now obviously dead, but whom the song's main character ironically continues to believe in out of an inner need for "protection." ("Can you protect me when I'm wrecked," he states, exposing the believer's motivation, but the person he's supposedly asking for protection is dead.)
Most chilling line: "Clear all your sins, Get born again...just repeat a couple lies..."
A clear reference to the evangelical movement saying that you will be saved by merely believing and repeating the words of a "Sinner's Prayer" asking Christ to forgive you for your sins, stating that you believe he is Lord and/or rose from the dead, and accepting him into your heart. The song is a very sad/cutting repudiation of the causes and consequences of wishful religious thinking.
As the early christian writer Paul said, "If there is no resurrection, then of all men we are most to be pitied." This song, which holds a very different worldview from Christianity, takes that statement to be true. (As in, there is in fact no resurrection, and believers are sadly deluded and to be pitied for their psychological need for reassurance).
Ultimate reading that I take from this song: I think they are implying,
"Sorry that your teddy bear is dead...You're on your own, kiddo." Ouch.
