Why was there an intense need to get Paul's letter to the Galatian assemblies?
The Galatian assemblies were being bombarded by Judaizers who wanted them to return to the Law, so Paul had to get his letter to them before it was too late. He wrote under intense urgency, even printing it in large block letters himself because of poor eyesight rather than waiting for a secretary.
Les explains that this little letter of Galatians, only six chapters long, was written under such duress that Paul 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 it up to the Galatian assemblies. Those congregations were being bombarded by Judaizers to come back under the Law, and it exercised the apostle to the point that he had to sit down and get the letter to them before it would be too late. Les also notes that the same kind of bombardment exists today, as most people want to do something to merit favor with God, but God will have none of it. The letter's constant warning is that believers are not under Law but under Grace, and should not let anyone pervert the Gospel by adding something to it. Chronologically, Galatians was written probably a couple of years before the Corinthian letters, and Paul's New Testament books are not in the order they were written.
