Since mankind was the second recorded “order” of creation, after the angels, it would seem we were created, in part, as a response to the angelic conflict. With Lucifer railing accusations towards God, about His fairness, etc., as portrayed especially in Job, it would seem God’s reply to Satan is that you are wrong, I am right, man in his freedom will prove it.
No matter how bleak this world appears, God’s love will endure, transform, sustain and overcome any and all attempts to thwart or counterfeit the real deal.
