During his travels, Paul heard about the lies that were being spread in Galatia. He heard about how this false teaching was impacting the church that he loved, so he wrote them a letter. In this letter, he called out the foolishness of this new teaching and reminded them of his own past experiences with the law. He reminded them that it is in Christ that we find our righteousness, not the law. And he shared his heart for them, reminding both them and us of the importance of walking according to The Holy Spirit, not the flesh.
