We find this Scripture also in James 4:10, but Peter gives us a chance to hear about how God will lift us up.
In this Scripture we read in Peter’s final exhortation that we need to beware because Satan is like a roaring lion. We are called to be alert and disciplined and to resist him. We are assured that even though we may be suffering a little while there will come a time when we will be restored and established once again. It is a strong encouragement to a people who needed to hear that they would be lifted up in a time of much confusion and persecution.
He then ends the letter with greetings including one to the church in Babylon. What does he mean Babylon? It is generally thought, and I agree, that he is referring to Rome. This thought will come in handy in Revelation because we often see a reference to Babylon which we know probably means Rome. He tells us to greet each other with a kiss. What a nice thought.
