'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

“Life” in the Bible has reference to what we love, to our affections, because what we care

about actually makes us who we are. “Light” has to do with our thinking, our intellect –

which is not life itself, but defines and guides our lives. This verse, then, in saying “in

him was life,” reveals that it is divine truth that inspires our feelings, that makes us want

what is good. And when we want what is good, that will be “the light of men,” inspiring

us to seek and understand true ideas that can help us actually be good and do what is

good.

So divine truth – the exquisite expression of the Lord’s love – is not only the driving

force behind creation, it is also the agent that creates our own internal lives, inspiring our

desires for good and through them our understanding of what is true.
