2 Peter 1:12-16

You know these things, and you are very strong in the truth, but I will always help you remember them. I think it is right for me to help you remember as long as I am in this body. I know I must soon leave this body, as our Lord Jesus Christ has shown me. I will try my best so that you may be able to remember these things even after I am gone. When we told you about the powerful coming of our Lord Jesus Christ, we were not telling just clever stories that someone invented. But we saw the greatness of Jesus with our own eyes.
