THE THINGS WE MUST NEVER FORGET: LIFE LESSONS FROM SECOND PETER - Faith isn’t self-sustaining. It must be fed by knowledge and knowledge must be made useful through self-control. That’s because our own unguarded reflex desires will lead us into error before the knowledge we have in our heads gets enough of a voice to make a difference. The Apostle Peter knew all about the highs and lows of following Jesus and in this passage takes us through a very down-to-earth faith maintenance process. There is always the need for the reminder to “make every effort” to supplement our faith.
