Galatians 5

http://www.esvbible.org/Galatians+5/

Paul tells the Galatians that Christ freed you to give you the benefits of freedom, but if you reject this freedom by enslaving yourself to the laws, then you cut yourself off from Christ, and, in doing so, fall from God's favor. As far as Jesus is concerned, it does not matter if you follow some of Moses' rules, like circumcision, until they get in the way of your faith in Him when they hinder the relationship. Paul wonders who it was that influenced the Church of Galatia so greatly as to re-believe in Moses' teachings to gain God's favor. To further convince them who they deal with, Paul tells the Galatians that the people who mislead them do not come from God as Paul does. He says that yeast quickly spreads through dough. It only took a few people to start believing the misleading words, and soon the belief spreads throughout the whole church. On the other hand, do not use the freedom to live in corrupt nature. Even Moses' Teachings boil down to loving your neighbor as yourself. There are two opposing natures at work inside of you, according to Paul: the spiritual nature and the corrupt nature. They always oppose each other and desire the opposite of what the other wants. The promise made to Abraham essentially says that after we accept Jesus as our Lord and Savior, we can more easily follow our spiritual nature. When we do so, we no longer need to follow Moses' Teachings. The effects of the corrupt nature (I would list my own examples, but Paul's seem to last even until today): illicit sex, perversion, drunkenness, envy, conflicts, jealousy, etc. keep you out of the Kingdom of God. The spiritual nature leads to the fruits of the spirit: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. There are no laws against the fruit of the spirit because they are good. If we live by our spiritual nature, we need to commit and conform to our spiritual nature.
