I think the best defense for God is “no one knows.” I can’t argue with that…but it doesn’t necessarily make it true. Yet, if we can’t understand God, then how do we know anything of him? Of his desire, his past actions, etc.?
I then think about the idea that God has given us free will, and we have strayed the path. This stance really makes God to seem like a trickster - that our existence is merely a game to him. Who is good enough. Who has more faith. This is absurd to me.
What I think is truly valid, and deserves my thoughts & time, is the life of Jesus. Regardless of whether this was a real man, or simply an idea, to try and live your life in that sense means more than anything else about Christianity. The thing is, it’s nothing new - many religions and non-religions have stated the same.
