ANSWER: This is another figure for denoting a moral likeness to God. They who have Christian love, holiness, justice, and truth have a nature like God's nature. To insist that they literally have his nature is to insist that they are gods. Many difficulties are surmounted and many errors are avoided by the exercise of reason in discriminating between the literal and the metaphorical in the Holy Scriptures.
