as children of obedience, not conforming yourselves according to your former lusts as in your ignorance,
Here a question arises, — Since he addressed the Jews, who were acquainted with the law, and were brought up in the worship of the only true God, why did he charge them with ignorance and blindness, as though they were heathens? To this I answer, that it hence appears how profitless is all knowledge without Christ. When Paul exposed the vain boasting of those who wished to be wise apart from Christ, he justly said in one short sentence, that they did not hold the head. (Colossians 2:19.) Such were the Jews; being otherwise imbued with numberless corruptions, they had a veil over the eyes, so that they did not see Christ in the Law. The doctrine in which they had been taught was indeed a true light; but they were blind in the midst of light, as long as the Sun of Righteousness was hid to them. But if Peter declares that the literal disciples even of the Law were in darkness like the heathens, as long as they were ignorant of Christ, the only true wisdom of God, with how much greater care it behoves us to strive for the knowledge of him!
