Peter’s perspective on the End Times is the sort of key or angle of approach for this series. He and the other leaders in the very early church are almost obsessed with the End Times, even to the point that it was a problem for them that had to be addressed in Paul’s letters to the Thessalonians. But there was a reason they were so focused on the End Times. They’re the point.
Everything Peter hoped for, his whole perspective on the coming of the kingdom of God, he figured out at he meditated on and studied Scripture regarding God’s victory at judgment. He states that we have the prophets, an even more certain and reliable source for what is coming than the transfiguration.
