Are miracles through keeping the Law or through faith?

Les explains that the question is whether the one who ministers the Spirit and works miracles among them does so by the works of the Law or by the hearing of faith. He says they could not perform any miracles under the working of the Law; it was impossible. But when the Holy Spirit activated the hearts and minds of those pagan Galatians and others throughout the Roman Empire, it produced a miraculous transformation from paganism with its idolatry and immorality. Les calls that a miracle in itself, and he notes that in the early church there were no doubt other manifestations of the miraculous, though Paul does not explicitly delineate them. The test remains: if you have witnessed a miracle, was it 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, and we come under grace and out from under the Law by faith, plus nothing. Galatians warns against being suckered into a works religion; it is grace through faith, plus nothing.
