There are those who think that they have been born again who have not rid themselves of the things mentioned in that scripture. Instead of questioning their salvation, Peter tells them to bear fruit in keeping with their new identity in Christ.1 Peter1:23 For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.
Therefore(those Peter has described as born again), rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind. 2 Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation,
