Robert Traill (Sermons from 1 Peter 1:1-4), Works 4:75:
Sanctification differs greatly as to the persons that are partakers of it; and it differs greatly too as to the same man: for a true believer, a truly sanctified man, may be more holy and sanctified at one time than at another. There is a work required of us, to be perfecting holiness in the fear of God, 2 Cor. 7:1; but we are no where required to be perfecting righteousness in the sight of God. For God hath brought in a perfect righteousness, in which we stand; but we are to take care, and to give diligence to perfect holiness in the fear of God. A saint in glory is more sanctified than ever he was, for he is perfectly so; but he is not more justified than he was. Nay, a saint in heaven is not more justified than a believer on earth is; only they know it better; and the glory of that light in which they see it, discovers it more brightly and more clearly to them.
