Matthew Poole and continuators on 1 Peter 1:14

14 As obedient children , not fashioning your selves according to the former lusts , in your ignorance .

Gr. Children of Obedience, by an usual Hebraism for obedient Children. So Children of Disobedience, Eph. 2.2. Col. 3.6. and this we may understand either absolutely, Children of obedience for obedient Persons; or with relation to God, obedient Children of God; and then the Apostle perswades them to their Duty by an Argument taken from their Adoption; being the Children of God, he would have them behave themselves obediently, as becomes them in that Relation.

Not accommodating, not conforming your selves, not shaping, or ordering your Conversation. See the same word, Rom. 12.2.

The Lusts you formerly indulged your selves in. See Ephes. 4.22.

Your Ignorance of Christ and the Gospel, q. d. not fashioning your selves according to those Lusts you lived in, when you were ignorant of Christ. He distinguisheth between the time of their Ignorance, and of their Illumination. Another Age requires other manners. They formerly lived according to the Dictates of their Lusts, but now ought to live according to the VVill of Christ. See v. 18. Acts 17.30. Ephes. 4.17, 18.
