2 Peter 1:14-16

knowing that the laying aside of this earthly tent of mine is imminent, as our Lord Jesus Christ has made clear to me. Moreover, I will diligently endeavor [to see to it] that even after my departure you will be able, at all times, to call these things to mind. For we did not follow cleverly devised stories or myths when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of His majesty [His grandeur, His authority, His sovereignty].
