God overrules for good the activities of those who teach false doctrine. In the days of the apostles, for example, we see these activities being overruled to the production of some of our foundational New Testament documents. Galatians is the prime example. The heresy it combats is, in its essence, widespread, and because of that, the letter is no less necessary now than it was 2,000 years ago. It gives us a very clear answer to that most vital of questions: How, as sinners, can we come to be right with the God against whom we have sinned? Nor does it leave it off before it has answered the related and no less important question: How, having become right with God, are we to progress in our Christian lives?
