So it is not really a surprise that men make really foolish choices as these Galatians did, however exasperating it may have been to Paul. The history of the Christian church in the world is, in large part, the history of this same stupidity.
But, it is very interesting to notice the specific point Paul makes here about the grip that man's natural religious ideas have upon the human soul and, accordingly, how hard it is for people to hold on to the pure gospel. A drug addict may continue to use drugs even after his life has been devastated by his drug use because, after all, he has become physically and psychologically dependent upon them. A woman may return to a violent and philandering husband over and over again because she is afraid to leave him or because she is afraid to be alone. But, why would a Christian who had tasted the fresh air of the gospel go back to the putrid atmosphere of works and human performance?
