The Second Epistle of Peter was also written by the apostle Peter in the middle of the first century. It warns of false teachers who had come into the Early Church and urges Christians to be brave and patient.

2 Peter 3

3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
