For this very reason, make every effort to supplement your faith with virtue, and virtue with knowledge, and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, and godliness with brotherly affection, and brotherly affection with love. For if these qualities are yours and are increasing, they keep you from being ineffective or unfruitful in the knowledge of our Lord Jesus Christ. 2 Peter 1:5-8
There is a conscious effort to the life of a Christian once he has been awakened. Both justification and sanctification are initiated and accomplished by the power of the Holy Spirit, not by us; but there is an added responsibility on the child of God once he has been educated by the Spirit and begun to be like Christ. We are to work together with the Spirit, to “work out what he has worked in” (Chambers) even as the Spirit Himself works the purification of our hearts (Philippians 2:12-13). The mark of a partially sanctified heart is that it wants to be more sanctified, and thus moves to participate in the continuing sanctifying work that the Spirit oversees from start to finish (Philippians 1:6).
A good way to conceptualize this is comes from the term “supplement” ( epichorēgeō – “supply, provide, furnish”) in 2 Peter 1:5. We are to nourish and feed our faith with these things – virtue, knowledge, self-control…they are the nutrients that help faith grow. Imagine a man who has just come out of a heart attack coma. Once he realizes he has been in a state of near-death, he must eat, drink, take vitamins to restore his health and energy. When he is stronger, he must then begin to exercise, and mind hid diet, and in general change the lifestyle behaviors that contributed to the heart attack. Consciousness brings with it a responsibility to work toward the change of his body. A man who continued to sit on his couch and eat cheeseburgers and neglect his heart attack medicine would deserve a second heart attack.
Likewise for the person who has been awakened by the grace of Christ. Upon realizing that he has been quite spiritually ill up to that point in his life, he must immediately take actions to supply his new faith with nourishment. Each of the qualities in Peter’s list comes from God, but is manifested through the struggle and decision of the man. If we know that God has given us by his grace the precious gift of belief, the only response is to do everything in our power to nourish, protect, and supply that belief, that it might grow strong and take inseparable root in our hearts.
Let the man who has been saved from heart attack supplement healthy living and medicine, and let the man who has been saved from sin supplement the grace of God with every effort to make his own faith in God grow.
