Found just once in the New Testament (Rom. 12:6), the Greek noun “analogia” meant “proportion” or “right relationship.” Those who had the spiritual gift of prophecy were to use it in “proportion” to their faith.
As discussed in this author’s online Bible commentary on Rom. 12:6-8, there is disagreement as to what this means but “one reasonable explanation is that these Christians were to use their gifts to the best of their ability. When prophecy was properly used, the church was edified, exhorted, and comforted (1 Cor. 14:3-4). Because Christians are members of one body and severally members one of another (verses 4-5), not using this gift for edification, exhortation, and comfort was unthinkable.”
