2 Peter 1:5-7 For this very reason, make every effort to supplement your faith with virtue, and virtue with knowledge, (6) and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, (7) and godliness with brotherly affection, and brotherly affection with love.
These verses are an exhortation by Peter for believers to cooperate in their own sanctification. Grace through the indwelling Holy Spirit is the engine that drives sanctification, but believers are not mindless robots that are powerless to act on their own. They are new creations in Christ that are led by the Holy Spirit, but they are in control of their actions and behavior. Therefore, Peter tells believers to, “make every effort” and lists the desired attributes they should cultivate. Notice the list of attributes is not a legalistic do and don’t list, but are qualities that flow from the heart and are a reflection of internal ethical and spiritual character. They are an expression of the new covenant internal religion of the heart rather than the external religion of the Old Covenant. Peter points to the importance of knowledge. This Biblical knowledge enables believers to understand and follow the righteous leading of the indwelling Holy Spirit.
