Peter began his second letter by telling us that God has given us everything we need to a godly life, but we must make an effort to actualize godliness. One of the ways we do this is by adding knowledge to our developing traits. This has nothing to do with our IQ. It means we want to follow Jesus and learn from Him, study His life, and obey His teachings — coming to know about Him, coming to know Him, and coming to know His ways better each day.
