When we try to turn from God and his gospel, it is like returning to a fifthly orphanage, the pit. This passage is all about learning to live as God’s children, in the freedom of grace and in the love of the Father.
In these verses, Paul opens up his heart to his spiritual children, the Galatians. He speaks as a shepherd, as father, and even using the language of a gentle mother. Even though Paul has rebuked them earlier, the language is of friendship and family here.
