Just wrapped up my study of Galatians. I love this final comment from F.F. Bruce. So true…
The religious mind is prone to subject itself to regulations; the liberating gospel of sovereign grace is too ‘dangerous’ to be allowed unrestrained course. As Paul became less a figure of controversy, as his memory was venerated and his writings canonized, his teaching was overlaid with a new legalism. When, from time to time, someone appeared who understood and proclaimed the genuine message of Galatians, he was liable to be denounced as a subversive character—as, indeed, Paul was in his own day. But the letter to the Galatians, with its trumpet-call to Christian freedom, has time and again released the true gospel from the bonds in which well-meaning but misguided people have confined it so that it can once more exert its emancipating power in the life of mankind, empowering those who receive it to stand fast in the freedom with which Christ has set them free.
