If you remove the idea that 'God is good' and say 'we were created with purpose' it raises some questions
If humankind, and even animal kind, were designed with a spectrum between good and bad, smart and dumb, healthy and unhealthy, the question would then be why?
If everyone was made perfect, it would be a boring story. Are we designed as entertainment? A social experiment of sorts?
How will the humans cope with rapists living among them? Murderers? Cheaters? Liars? Will the heroes raise up and beat them?
Is it all designed? Removing the idea that God created something perfect and 'sin' invaded leaves us with the reality that we were purposefully designed to be both good and bad. The question then is why?
