“Because of that experience, we have even greater confidence in the message proclaimed by the prophets. You must pay close attention to what they wrote, for their words are like a lamp shining in a dark place—until the Day dawns, and Christ the Morning Star shines in your hearts.”
2 Peter 1:19 NLT
Speaking of the Transfiguration, Peter highlights how his experience effects his own convictions about the Scriptures. He commands that, due to his stature in the church, his experience be seen as confirmatory of the Biblical narratives. This is particularly difficult interesting given the holy nature of the Bible. Peter strikes a curious balance between understanding the scripture as holy, and understanding his own experience as holy. The metric he uses to elevate his experience is Scripture itself. Peter notes that his experience is in line with previously established truths in the texts. Therefore his own experience can actually elevate those truths. He is not claiming that his experience supersedes those truths. If his experience were to create a new revelation, then this would make violate scripture. When we see this passage, we have to be clear that Peter is allowing his testimony to elevate a pre established truth. He is not creating a new truth with his testimony.
