Ok
Firstly, I don't think in terms of 'existence' but rather that God just 'is'. I think that's common for most Christians. He didn't need to create anything he just 'did', because that's his nature, it's what he does. Like I like to annoy ppl too much
it's his purpose and his definition. What's the purpose of a light bulb? A: To be a light bulb.
Then purpose could be thought of as relevance and impact. Or potential impact in the case of a non believer. To me that's like choosing life. The point of God is to offer a way to choosing life. It's not the only way to skin a cat, but it's a way.
