2 Peter 1:17-18
The Transfiguration
17 For he received honor and glory from God the Father when the voice came to him from the Majestic Glory, saying, "This is my Son, whom I love; with him I am well pleased." 18 We ourselves heard this voice that came from heaven when we were with him on the sacred mountain.
St. Peter in 2nd Peter tells about Jesus receiving honor and glory from God on the sacred mountain and (God) saying "This is My Son, whom I love; with Him I am well pleased...
Three other more detailed accounts of this story are in Matthew 17:1-9, Mark 9:2-9, and Luke 9:28-36...Three Gospel writers write about the Transfiguration and how God tells Peter, James, and John "This is My Son, listen to Him"...
As God told the disciples, we too should be listening to Him...
