1:19 more sure word. As sure as Peter was of what he had seen and heard, this was only his own experience, and could only be given as a personal testimony to others. Thus, he stressed that God’s written Word, available to all in the holy Scriptures, was more sure than any personal experience he or others might have. It is not in Peter or Paul as men, no matter how sincere or holy they may be, that we must trust, but in Christ as revealed (not in our experience either!) in God’s written Word.

1:19 day star. At His return, Christ will be recognized as the true “bright and morning star” (Revelation 2:28; 22:16).
