1 Peter addresses Christians who have known suffering and persecution to a degree that we will never know. In 2 Peter, Peter was very concerned that those who deny Christ’s return should be withstood and that the church could be confident that Christ has not abandoned them. The theme of Jude is similar and also points Christians towards the evidence of believers who heard Jesus speak, to enable them ‘to fight on for the faith which once and for all God has given to his people’.
