What does 2 Peter 2:17-22 reveal about who God the Father is? God punishes sin. The blackest darkness is reserved for the false teachers (2 Peter 2:17). God is knowable. He reveals himself to man (2 Peter 2:20). God is just. Those who have greater knowledge and power will be judged accordingly (2 Peter 2:21).
17 These are waterless springs and mists driven by a storm. For them the gloom of utter darkness has been reserved.
