2 Peter 1:10-19 New American Bible (Revised Edition) (NABRE)
10 [a]Therefore, brothers, be all the more eager to make your call and election firm, for, in doing so, you will never stumble. 11 For, in this way, entry into the eternal kingdom of our Lord and savior Jesus Christ will be richly provided for you.
Apostolic Witness. 12 [b]Therefore, I will always remind you of these things, even though you already know them and are established in the truth you have. 13 I think it right, as long as I am in this “tent,”[c] to stir you up by a reminder, 14 since I know that I will soon have to put it aside, as indeed our Lord Jesus Christ has shown me. 15 I shall also make every effort to enable you always to remember these things after my departure.
16 We did not follow cleverly devised myths when we made known to you the power and coming[d] of our Lord Jesus Christ, but we had been eyewitnesses of his majesty. 17 For he received honor and glory from God the Father[e] when that unique declaration came to him from the majestic glory, “This is my Son, my beloved, with whom I am well pleased.” 18 We[f] ourselves heard this voice come from heaven while we were with him on the holy mountain. 19 Moreover, we possess the prophetic message that is altogether reliable. You will do well to be attentive to it, as to a lamp shining in a dark place, until day dawns and the morning star rises in your hearts.
