Cover art for M23 lyrics by Starflyer 59

"Can I rely, can I? In the twinkling of an eye... Of an eye, we'll rise

So I'll rely on Christ In the twinkling of an eye We'll rise"

Definitely referring to the rapture in the Bible, where Jesus Christ comes for the church in a quick manner like the "twinkling of an eye." I believe the song is about having faith in that.
