1:12-14 Though, as a sinner, the apostle could only rejoice and glory in Christ Jesus, yet, as a believer, he might rejoice and glory in being really what he professed. Conscience witnesses concerning the steady course and tenor of the life. Thereby we may judge ourselves, and not by this or by that single act. Our conversation will be well ordered, when we live and act under such a gracious principle in the heart. Having this, we may leave our characters in the Lord's hands, but using proper means to clear them, when the credit of the gospel, or our usefulness, calls for it.

13. We write none other things (in this Epistle) than what ye read (in my former Epistle [Bengel]; present, because the Epistle continued still to be read in the Church as an apostolic rule). Conybeare and Howson think Paul had been suspected of writing privately to some individuals in the Church in a different strain from that of his public letters; and translates, "I write nothing else to you but what ye read openly (the Greek meaning, 'ye read aloud,' namely, when Paul's Epistles were publicly read in the congregation, 1Th 5:27); yea, and what you acknowledge inwardly."

or acknowledge—Greek, "or even acknowledge." The Greek for "read" and for "acknowledge" are words kindred in sound and root. I would translate, "None other things than what ye know by reading (by comparing my former Epistle with my present Epistle), or even know as a matter of fact (namely, the consistency of my acts with my words)."

even to the end—of my life. Not excluding reference to the day of the Lord (end of 2Co 1:14; 1Co 4:5).
