Galatians - D a Waite - Bog

The Galatian Problem: The Galatian Christians believed that, though they were saved by God's grace through faith in Christ, they must be sanctified by works through keeping the Law of Moses.
The Galatian Solution: Paul's soution to these Galatians was very simple. It was in two parts. (1) Since God had saved them by His grace through faith, they must be sancitified by grace through faith also and not by keeping the Mosaic Law. (2) The Judaizers who were teaching them this error were preaching "another gospel" and were therefore cursed by God. Paul repeated this condemnation two times for emphasis (Galatians 1:8-9)
The Galatian Application: We who are saved in the Age of Grace, like the Galatian believers, were saved by God's grace through faith in Christ. We are to be sanctified day by day also by God's grace through faith and dependence upon the power of the Holy Spirit. This means that we are not under any of the three parts of the Mosaic Law. Those who differ with this are preaching "another gospel" and are also under God's curse.
