This chapter of Galatians lays out God's sentence on those holding and then on those teaching this wicked doctrine that we must do additional things to be justified. The verdict is...this doctrine is not from God...the sentence is...you are not saved if you hold this. The sentence for those who were teaching this was that it was leaven and they needed to bear God's judgement and be removed from the assembly and he wished they would cut themselves off - separate themselves from the body of believers.

Then the apostle by the Spirit goes into antinomianism and the evil that this 'other side of the ditch' would be and proclaims that those who practice the deeds of the flesh are not saved either. Then there is a reminder that we are purchased by God and how we walk today is not be a law...but by the Spirit of God alone.
