The truth alone sanctifies

"The power that sanctifies us is no other power but the power of the cross of Christ; and the glory to which we are conformed by the Spirit in beholding it, is the glory that shines in Christ crucified; and we are raised up to walk in newness of life, no otherwise but together with Christ, and by the power of his resurrection, 'who was delivered for our offenses, and raised for our justification,' and by that blood of everlasting covenant, by virtue of which he came again from the dead: and therefore they seek sanctification where it is not to be found, who seek it not in this truth; and they seek it in vain, who seek it not by that belief of this truth, whereby we receive the remission of sins, and are justified." - John Glas, The Works of Mr. John Glas, pg. 146
