Further back than our roots
A question for you - if you can think of it as a creature of time. What was God doing before creation? A tricky concept as time itself didn't exist then. Now I should say that this thought occurring to me is not original. It was sparked by reading Frank Viola - although it's bound to have occurred to others since time began.
So creation (including time) doesn't exist yet. But God does. And He has the perfect relationship within the Godhead. I won't get sidetracked by the issue of the Trinity. I used to have analogies - but in hindsight, all they did was try and bring God down to a level I could understand. So there's God, with this perfect relationship of love going on. Did He have a brainwave? Or a meltdown? He decided to create a being (that's you and me) to share this loving relationship.
From what the Bible says, He still considers it / us as worthwhile - even after all the issues we've caused. What does that tell us about His love? The hymn Amazing Grace doesn't even come close to doing it justice.
