How do Galatians and Romans compare to each other?
Galatians is introductory, like an artist's pencil drawing, while Romans is the final oil painting on canvas. Galatians does not go into the deep things of Romans. Although Galatians should have been in front of Romans, it has a divine purpose in its current placement after the two letters to the Corinthians.
Les explains that Galatians should have been in front of Romans, because if you compare it to an artist, Galatians is more or less his pencil drawing of what he has on his mind, and Romans is like the final paint and oil on canvas. He says Galatians is so introductory that it doesn't get down into the deep things of Romans, and yet it has its divine purpose for being exactly where it is, following the two letters to the Corinthians. Les also notes that all of Paul's letters have always been in that order in every copy of the New Testament, suggesting the Holy Spirit laid out the format of these epistles.
