2 Peter 1:12
Therefore I intend always to remind you of these qualities, even though you know them and are established in the truth that you have — Peter's repeated teaching is not redundant but remedial, recognizing that settled doctrine must be constantly renewed in practice. The established truth (stērizō) provides stable foundation, yet continual exhortation prevents spiritual complacency. The pastoral insistence reflects the perpetual human tendency toward forgetfulness.
