Context Reading
9But now that you know God, or rather are known by God, how is it that you are turning back to those weak and worthless principles? Do you wish to be enslaved by them all over again? 10You are observing special days and months and seasons and years! 11I fear for you, that my efforts for you may have been in vain. 12I beg you, brothers, become like me, for I became like you. You have done me no wrong. 13You know that it was because of an illness that I first preached the gospel to you.
