More on act of Worship

I`ve been thinking more about the phrase “an act of worship” since reading the comment left on my first one on the subject.
I think my dislike of the phrase was because I was using the interpretation of the word act in the sense of something not real. And to me that was wrong as worship is something real.
It`s something that is important to my life and not just something to be acted at on a superficial level which was the way the phrase had always seemed to me. I realise that worship is an activity involving heart, mind and soul… but body?.... (unless one is clapping, …) how? Or am I again thinking of a word in the wrong way of its meaning?
Notice the use of `was`, I think on this phrase I`ve now been converted!, but not on `lost`.

Strange isn`t it, how one can get a phrase and only look at it one way, and not see other possible meanings.
Think I shall have to study English better!
