It was written as an answer song to John Lennon's "God", having the same kind of lyrical structure. It also contains an attack on American biographer Albert Goldman, on the following verses, by way of Lennon's song "Instant Karma!":

Additionally, the song alludes to Bruce Cockburn's "Lovers in a Dangerous Time", in the lyric "Heard a singer on the radio late last night/He says he's gonna kick the darkness 'til it bleeds daylight."

The song is a departure from the folksy-roots rock sound of the album's other studio recordings and is an introduction to the darker sound the band would adopt following the release of their next album, Achtung Baby.

A remix entitled the 'Hard Metal Dance Mix' was released on the "When Love Comes to Town" single.

"God Part II" was only played on the Lovetown Tour in late 1989 and early 1990. It was played at 36 of the 47 concerts; it debuted at the first show of the tour on 21 September 1989 in Perth and was last performed at the second-last show of the tour on 9 January 1990 in Rotterdam. It was one of six songs to be used as concert openers on the tour, opening two concerts: 26 December 1989 in Dublin and 5 January 1990 in Rotterdam. For these two performances, its heavy bassline was linked to a recording of the Rolling Stones' "Sympathy for the Devil".

A performance from a Dublin show later saw light on the release Live from the Point Depot.
