12 You are holding firmly to the truth that you were given. But I am still going to remind you of these things.
13 In fact, I think I should keep on reminding you until I leave this body.
14 And our Lord Jesus Christ has already told me that I will soon leave it behind.
15 That is why I am doing my best to make sure that each of you remembers all this after I am gone.
16 When we told you about the power and the return of our Lord Jesus Christ, we were not telling clever stories that someone had made up. But with our own eyes we saw his true greatness.
17 God, our great and wonderful Father, truly honoured him by saying, “This is my own dear Son, and I am pleased with him.”
18 We were there with Jesus on the holy mountain and heard this voice speak from heaven.
