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. For whoever lacks these qualities is so nearsighted that he is blind, having forgotten that he was cleansed from his former sins. (2 Peter 1:5-9)
The Greek word translated “supplement” in the English Standard Version comes from two words that mean “leading a chorus” (Robertson’s Word Pictures). The idea is that the Christian virtues in this passage are not to be added to one another, as the KJV and the NIV have it, but to supplement or complete one another as the voices in a chorus do. The balanced, mature Christian life has these virtues in harmony. Faith, for instance, must be in harmony with knowledge, self-control with steadfastness, etc.
That godliness must be in harmony with brotherly affection (philadelphia) is particularly striking. The noble desire for godliness, in isolation from the other virtues, has led many to ungodly extremes. Monastacism in its various expressions is one example. Monks have sought to free themselves from sinful temptations by isolating themselves from the world and others, only to find, as Jerome did, that they cannot escape their own thoughts! Some, in seeking personal godliness, have become judgmental of others, lacking in brotherly affection. Nothing is more cacophonous than supposed godliness without brotherly affection or kindness (NASB). It’s like a novice putting a bow to a violin!
One final voice, standing next to Brotherly Affection, completes the chorus: LOVE. Brotherly affection is that deep bond between believers in Christ, yet our love must extend beyond the bounds of our spiritual family. Our Lord commanded that we love even our enemies (Matt. 5:44; Luke 6:27, 35). That love of the will (agape), is also needed in cultivating brotherly affection. That's why the two are often mentioned together (Rom. 12:10; 1 Thes. 4:9; 1 Peter 1:22; 2 Peter 1:7)
Meditating on how all the voices in this chorus of Christian virtues should sound together is a good exercise. We must remember, however, that it is not by the exertion of our will that we can put these virtues in balance. It is the work of the Holy Spirit. Paul calls them “the fruit of the Spirit” (Gal. 5:22), and he exhorts us to “walk in the Spirit” (Gal. 5:16 compare Rom. 8:4). Whenever we find that our spiritual life is out of balance – and it happens to every Christian for time to time – we need to refresh our relationship with Christ through the work of the Holy Spirit by means of prayer and the Word. We need to quiet ourselves before the Lord for as long as it takes for renewal.
The Christian’s life is to be a chorus of praise to the grace of God. Let’s make sure all the voices are singing together.
