As Paul continues to fight against the strong religious atmosphere in Galatia, he brings up this matter of faith in contrast to the works of law.  What is this faith that he is talking about?  I submit that he isn't talking about having faith that you'll score the winning touchdown or having faith that your project will succeed.  Rather, the faith in Galatians 3 is much more crucial not just for our initial salvation, but also our going on in our Christian life.
