What did the Holy Spirit do in the hearts and minds of the Galatians and other Romans?

Les explains that when the Holy Spirit activated the hearts and minds of those pagan Galatians and others throughout the Roman Empire, the result was a miraculous transformation from paganism with all its excesses, idolatry, and immorality. They stepped out into a whole new lifestyle, which he calls a miracle in itself. Les notes that miracles could not be performed under the working of the Law; that was impossible. Instead, the Spirit was activated by faith. The early church no doubt had other manifestations of the miraculous, though Paul does not explicitly delineate them. The key question remains whether a miracle came through keeping the Law or through the manifestation of the Spirit activated by faith. Les emphasizes that we are not under Law but under grace, saved by grace through faith, plus nothing.
