I can't resist -
To praise the lord, one passes the ammunition, or so it has often seemed with many religions' followers - even though I know the words don't actually say that.

"Praise the Lord and Pass the Ammunition" is an American patriotic song written by Frank Loesser and published as sheet music in 1942 by Famous Music Corp. The song was a response to the attack on Pearl Harbor that marked United States involvement in World War II.
The song describes a chaplain ("sky pilot") being with some fighting men who are under attack from an enemy. He is asked to say a prayer for the men who were engaged in firing at the oncoming planes. The chaplain puts down his Bible, mans one of the ship's gun turrets and begins firing back, saying, "Praise the Lord and pass the ammunition".

I used to be religious, and, while it was a long time ago, my memory is that, as a '50's catholic, I learned of god as a trinity. I had less of a sense of praising what I knew of the biblical god the father (looking back, I really had no connection to what I had been taught), and I never quite got the holy ghost, but I did admire god the son, Jesus: prayed to him and thought very well of him, which I think is a kind of praising.
I know more than I did then about a lot of religions and their adherents, including that not all adherents of even one religion are the same. I think 'praising' - other than repeating known and rote phrasing - would be different for individuals, in their thoughts, in their meditations.
