All Scripture is profitable for "doctrine"! The same order is observed throughout the Epistles, particularly in the great doctrinal treatises of the apostle Paul. Read the Epistle of "Romans" and it will be found that there is not a single admonition in the first five chapters. In the Epistle of "Ephesians" there are no exhortations till the fourth chapter is reached. The order is first doctrinal exposition and then admonition or exhortation for the regulation of the daily walk.
