As we finish up chapter one of our study through 2 Peter, Peter gives his reason for writing and the title of our series--he is writing to "stir them up"; to remind them of the things they already should know. Peter exhorts his readers that what they have heard of the gospel is not a fabricated story or myth, but that the prophecy and writings of God's Word validates its divine origin--that it is trustworthy because of all the prophecies that have come to pass.
