The Fall did not take God by surprise. He already knew what He would do in view of it and Who would do it. We have two good reasons why we can come to God: what Christ did for us, and what God did for Christ for what Christ did for us. Our attitude toward God, therefore, can and should be both reverential ( 1 Peter 1:17) and confident as we endure suffering for our faith. [source][source][source]
So far ". . . the ethical impact of the epistle barely begins to make itself felt. The call to action and to a holy and reverent life is general rather than specific. The imperatives of hope and of godly fear have more to do with eschatological expectations than with ethics, and more to do with the readers" relationship to God than with their relationships to each other or to their pagan neighbors."

"At this point ends what we may call the doctrinal section of the Epistle. St. Peter has been explaining the three Names [2], their three attributes, and their several relations. Here he passes to the practical Christian life, catching up and expounding the words hagiasmos [3], anagennan [4]." [5][source]
