Well, here's the deal with Galatians 4, it's all about freedom. Paul tells the Galatians that since they are children of God, they are no longer enslaved to their old ways. They can now be free in Christ. But, of course, there is a catch. Paul warns them not to go back to their old ways, because that would be like going back into slavery. So, if they want to be truly free, they have to remain in Christ. Well, there you have it, folks. Freedom isn't free, at least not in Galatians 4.
