Does God's Law trump man's law, page-82

Hi, How do you see 1 Tim 6:16 then?
16. Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting.
So the question arises, what is it that no man can approach, or hath seen etc. Is that referring to the actual Light (God's light) and not the one who it's talking about?

It also seems a bit odd that Jesus will be showing us himself. I may be reading it wrong but, it looks a bit like bragging.
Not to mention, the Jesus's first coming was all about showing us the Father.

Not a big deal, I just like to 100% understanding of verses like this.
