The Study of the Two Letters of Justification: Romans and Galatians In the epistle of the apostle Paul to the Galatians, the apostle Paul is concerned to defend the gospel. Jewish troublemaker were more striving for the law than for Christ. These thoughts spread in the assembly of Galatian and attack the basis of the gospel. Paul had to tell the Galatians clearly that their new ideas are wrong. One important topic of the Epistle of the apostle Paul to the Romans is the Gospel of God. This epistle to the Romans contains some instructions for believers. It explains the God's dealings with man and shows in instructive and exhorting form the appropriate behavior of those who have received the gospel. F. B. Hole explains in his exposition the justification by faith. It is a great help for understanding this important theme and the two epistles of the apostle Paul.
