That's pretty well articulated, but it is lacking. It shows for example how someone can go into science and keep their religious faith. It is lacking because it focuses on one narrow style of religious faith. May I propose an alternate?
"....It is equally mistaken to suppose that our scientific understanding of the impersonal principles according to which the universe works makes it either unnecessary or impossible to believe in the existence of three thousand gods under the all powerful Zeus who working both alone and in concert designed, made, and upholds it."
Let's not obfuscate fairly simple things with big sentences and long winded arguments. Okay?
Well if we are to entertain Lennox's quote, then we have to understand his world view. He studies ancient gods and claims that they all have theogeny, or an origin story, they are in effect "created gods". They are not eternal.
The "God" word in his definition (and mine) is the creator of this universe. The creator is himself not created, he is eternal. God also has no gender, I use the pronoun "he" because it is conventional. Whether there is more than one creator is not the point, for the sake of our discussion, let's equate God with "the creator of this universe". So it doesn't matter whether his name is Zeus or Jack or Daisy.
My point is I believe that there is an intelligent designer of this universe, this world didn't come from nothing, and I call this intelligent designer "God".
