But those who fail to develop in this way are shortsighted or blind, forgetting that they have been cleansed from their old sins.
So, dear brothers and sisters, work hard to prove that you really are among those God has called and chosen. Do these things, and you will never fall away.
Then God will give you a grand entrance into the eternal Kingdom of our Lord and Savior Jesus Christ.
Therefore, I will always remind you about these things—even though you already know them and are standing firm in the truth you have been taught.
And it is only right that I should keep on reminding you as long as I live.
For our Lord Jesus Christ has shown me that I must soon leave this earthly life,
so I will work hard to make sure you always remember these things after I am gone.
For we were not making up clever stories when we told you about the powerful coming of our Lord Jesus Christ. We saw his majestic splendor with our own eyes
when he received honor and glory from God the Father. The voice from the majestic glory of God said to him, “This is my dearly loved Son, who brings me great joy.”
We ourselves heard that voice from heaven when we were with him on the holy mountain.
Because of that experience, we have even greater confidence in the message proclaimed by the prophets. You must pay close attention to what they wrote, for their words are like a lamp shining in a dark place—until the Day dawns, and Christ the Morning Star shines in your hearts.
