To me that's saying, there is more to life than the Truth, and its manifestation. I'm not sure I agree that there is more. Certainly there are lies and errors, but I consider these as the spaces between truths.
God was not unable, He was unwilling.
I don't know His will, and I view any claims to such knowledge as requiring extraordinary substantiation.
