The Apostle Peter, under the inspiration of God, wrote of the Apostle Paul, “our beloved brother Paul, according to the wisdom given to him, has written to you, as also in all his epistles speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the scriptures” (2 Peter 4:15-16). These sentiments may be no more applicable to any of the writings of Paul than to the epistle to the Galatians. It is a book that raises questions about God’s law which untaught and unstable people twist to their own destruction.
At the same time, the book of Galatians is one of the most inspiring books, reassuring us of the promises of God that are ours by faith apart from works. God wants us to know that we are not inheritors of His promises by the works of the law, but by faith in Jesus Christ. We see clearly that the children of God are known not by their outward physical works, but by their inward beliefs in the cross of Jesus Christ, in the grace of God and its manifestation in their practice of love. In addition, Galatians makes clear the source of righteousness is no longer through the law, but rather the righteousness which is by faith.
