2 Peter 1: Keeping the Fire
2 Peter 1 explains why teaching and discipleship were always says an important part of the Christian community.
2Pe 1:12 Wherefore I will not be negligent to put you always in remembrance of these things, though ye know them, and be established in the present truth.
2Pe 1:13 Yea, I think it meet, as long as I am in this tabernacle, to stir you up by putting you in remembrance;
2Pe 1:14 Knowing that shortly I must put off this my tabernacle, even as our Lord Jesus Christ hath shewed me.
2Pe 1:15 Moreover I will endeavour that ye may be able after my decease to have these things always in remembrance.
2Pe 1:16 For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty.
Peter, as one of the disciples, knew Jesus before and after His resurrection. He was an eyewitness of the majesty of Christ. Therefore, he says that he would be negligent if you did not remind the people and stir them up because it is true. It is not simply a fable. It is something that is very important for them to know.
He also knows that he is going to die soon as Jesus showed him. In John 21:18, Jesus had told Peter that when he was older he would be taken some worry he did not want to go and have his arms stretched out. Clearly, this was alluding to crucifixion as John himself notes in verse 19. Because he understood that his death was imminent, he did not want the people to forget all of these important things after he was gone.
There are many religious movements or other types of cause-related messages that burnout after the first generation. Maybe those people were passionate, but they have a hard time regenerating that excitement in future generations. Peter explicitly says that he wants them to make sure that they were following the truth which he was an eyewitness of.
The implication for all of us is that we are a product of that truth. As Christians, we are still following that truth. Whatever, we ought to be grateful that Peter and the other early apostles were so dedicated to preserving the message among the brethren.
