Anyone out there have a clue what Thin Lizzy mean by their song Holy War?

Lyrics:

A sample:
If you will adore me
Bow before me and praise my name
If you place no god before me
Then all I have is yours to claim
And if God is in the heavens
Why did God let children die
If you don't ask these questions
There is no reasons why
We are chosen
We are one
We are frightened of no one
And no one will win this war
This is the way
This is the law


Holy War performed in concert, 1983. Hat tip Infidel Bloggers Alliance.
John Lennon and Jesus Christ. Sounds like the setup to some sort of joke. But, John had a love/hate relationship with Jesus, as detailed in the book The Gospel According to the Beatles by Steve Turner. The January 2007 Christianity Today has this excerpt.

A teaser paragraph:

Those close to the couple sensed that the real reason she [Oko] was concerned was that it threatened her control over John's life. If he became a follower of Jesus he would no longer depend on her and the occultists. During long, passionate arguments she attacked the key points of his fledgling faith. They met with a couple of Norwegian missionaries whom Yoko questioned fiercely about the divinity of Christ, knowing that this was the teaching that John had always found the most difficult to accept. Their answers didn't satisfy her, and John began to waver in his commitment.
