Hindrance from Obeying The Truth

Galatians 5:7-12

7  Ye did run well; who did hinder you that ye should not obey the truth? 
8  This persuasion cometh not of him that calleth you. 
9  A little leaven leaveneth the whole lump. 
10  I have confidence in you through the Lord, that ye will be none otherwise minded: but he that troubleth you shall bear his judgment, whosoever he be. 
11  And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased. 
12  I would they were even cut off which trouble you.
