Galatians 6

http://www.esvbible.org/Galatians+6/

Paul calls upon the Galatians to help each other in their spiritual journeys. If you see some one struggling with something along the way, point it out to them and help them through it so that they can grow closer to God. Do so in a gentle way, however, because you don't want them to withdraw into those ways of the corrupt nature. Additionally, be careful not to be tempted by such things. If anyone thinks you're important when you're really not, you only fool yourself. Examine yourself and be proud of your own accomplishments, but do not compare them to what others have done.

You reap what you sew. If you plant in your corrupt nature, you will harvest destruction. If you plant in your spiritual nature, you harvest eternal life. Sometimes, living always in the spiritual nature can feel exhausting, but if we stick with it, the end result is everlasting life. Do what is good for everyone.

Paul summarizes and tells them again that these false teachers tell them that they need to change their bodies in order to follow Christ. In reality, it is the heart that needs to change. The false teachers want the believers to circumcise themselves in order to brag about their bodies. Paul again proves that his cause comes from God when he tells them that all he wants to brag about is what happened on the cross. When Paul became a believer, he left his relationship with the world behind. Essentially, he doesn't care what the world thinks of him as long as he follows what God tells him to do, and he encourages all the other believers to do the same. It doesn't matter if you're circumcised or not. What matters is where your heart is.
