For it is God who is at work in you, both to will and to work for His good pleasure.
I understand that this question deals with infinite concepts and it's impossible for us to comprehend the mind of God as Isaiah 55:8 says:
For my thoughts are not your thoughts, neither are your ways my ways," declares the LORD.
Nevertheless, I feel I must seek an answer from which to base the purpose of my own actions. I am looking for opinions from others supported by philosophical reasoning or historical references, not necessarily facts straight from the bible.
This question is in a way asking why god created life at all. I've seen this question answered with a simple "because it pleases him," but that just doesn't seem satisfactory to me.
My hunch is that God created as an extension of his loving nature. 1 John 4:8 says that "God is love", and I know of no other scripture where God is described in such a way. It's clear to me that this love is referring to a love for others (rather than self-love) so that would be complete with the existence of the Trinity with no call for angels or man. For this reason, I feel angels and man were created with the intent of us taking part in this love and also showing his love as perfect by redeeming us despite our rebellion.
As 2 Corinthians 12:9 says:
And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness
TLDR: In what way does our ultimate existence please God? My tentative theory is that we are used to show his love as perfect and to take part in that love.
