Likewise, you younger ones, be subject to the elder. Yes, all of you gird yourselves with humility, to subject yourselves to one another; for "God resists the proud, but gives grace to the humble."
The sons of God were appearing before God in the book of Job, chapter one, and God --Satan also came with Him; and God said to Satan, Where have you been? And he said, Going to and fro throughout the earth, walking up and down in it. Here Peter tells us that your adversary, the devil, walking around like a roaring lion, just looking for whom he can devour. You have to be on guard. Be sober, be on guard and resist him.
