2 Peter 1:12-18

12Therefore I will not be negligent to put you always in remembrance of these things, though ye know them, and are established in the present truth. 13Indeed, I think it right, as long as I am in this tabernacle, to stir you up by putting you in remembrance; 14Knowing that shortly I must put off this my tabernacle, even as our Lord Jesus Christ hath shown me. 15Moreover I will endeavour that ye may be able after my decease to have these things always in remembrance.

16For we have not followed cunningly devised fables, when we made known to you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty. 17For 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. 18And this voice which came from heaven we heard, when we were with him on the holy mount.
