The Epistle to the Galatians is corrective rather than instructive. It was not simply to instruct the assemblies in the great truths of the gospel, as in the Epistle to the Romans; nor to unfold the truth of the church, as in the Epistle to the Ephesians; nor to present experience, proper to Christians, as in the Epistle to the Philippians. It was written to correct a great evil that had crept into the assemblies of Galatia. It has the same character as the Epistle to the Corinthians, but with this difference: the Epistle to the Galatians was written to correct legality, while the Epistles to the Corinthians were written to correct carnality or worldliness (1 Corinthians iii. 3). Though apparently so opposite, both evils are near akin inasmuch as both recognize the flesh. Legality is the effort to control the flesh by rules, and cultivate the flesh by religious ceremonies. Lawlessness is the indulgence of the flesh.
