2 Peter 1:17-18

2 Peter 1:17-18. For he received from God the Father honour and glory when there came such a voice to him from the excellent glory, this is my beloved Son, in whom I am well pleased. And this voice which came from heaven we heard, when we were with him in the holy mount.

Peter was not deceived about that matter; at the time, he and his fellow-apostles had been overcome by the too-transporting sight, but they all knew that it was no vision, or dream, or delusion, so Peter here speaks very positively concerning it. Why can we not receive the testimony of true witnesses such as Peter and the other apostles who sealed with their life’s blood the witness which they bore to their Lord and his truth?
