Why did Paul need to get his letter to the Galatian assemblies?
Paul needed to get his letter to the Galatian assemblies because they were being bombarded by Judaizers to come back under the Law. The urgent danger compelled him to write quickly, even printing in large block letters because of poor eyesight, so the congregations would be warned before it was too late.
Les explains that Paul was under such duress to get this letter written as quickly as possible that he did not even wait for a secretary to take dictation. Instead, he laboriously printed it in large block letters because of his poor eyesight, driven by the intense need to get the letter up to the Galatian assemblies, who were being bombarded by the Judaizers to come back under the Law. It exercised the apostle to the point that he had to sit down and get this letter to those congregations before it would be too late. Les also notes that this little letter is appropriate today because we are under the same kind of bombardment, and its constant warning is that you are not under Law but under Grace, so no one should pervert the Gospel by adding something to it.
