The Transfiguration of the Lord!
2 Peter 1:16-19
16For we did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty.17For when he received honor and glory from God the Father and the voice was borne to him by the Majestic Glory, “This is my beloved Son, with whom I am well pleased,”18we heard this voice borne from heaven, for we were with him on the holy mountain.19And we have the prophetic word made more sure. You will do well to pay attention to this as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts.
