Galatians 6:18 - Matthew Poole's English Annotations on the Holy Bible

The apostle closeth this Epistle with this prayer, as he generally concludeth all his Epistles, with wishing them grace, the grace of our Lord Jesus Christ; under which he comprehendeth all the effects of the free love of God upon believers souls, for the sake, and in and through the merits, of the Lord Jesus Christ: this he prayeth that they might feel in their hearts, and that it might be in their spirits, to quicken, strengthen, comfort, and establish them, according to the different manifestations of the Spirit of grace. It hath been said before, that we are not to look upon these dates of apostolical Epistles as part of holy writ, for in some of them there are manifest mistakes; but most think that this Epistle was written from Rome, while Paul was a prisoner there, who are in part guided to it from Galatians 6:17, thinking that it was written at a time when Paul was there suffering imprisonment. But of this there is no certainty.
