New Defender's Study Bible Notes
1:17 excellent glory. On the “holy mount” of Transfiguration (II Peter 1:18), the three disciples (Peter, James and John) actually saw Christ glorified, as He will be when He comes again in “power and great glory” (Matthew 24:30) and heard God the Father acknowledge His beloved Son from heaven (Matthew 17:5), just as He had done at His baptism (Matthew 3:17). Peter had also seen the resurrected Christ several times and had watched him ascend into heaven with the promise that He would return (Acts 1:11). Thus, Peter himself could have no doubt that He was the only true “God and Savior;” all else was myth and fable.
