Syntax of the Moods and Tenses in New Testament Greek

Of Syntax of the Moods and Tenses in New Testament Greek, the author writes:

Classified according to its intent, it belongs among the aids to the interpretation of the New Testament. It is designed to assist English-speaking students in the task of translating the Greek New Testament into English forms of thought and expression. The work has not been undertaken under the impression that grammar is an end in itself, or that a knowledge of it is the sole qualification for successful interpretation, but in the conviction that grammar is one of the indispensable auxiliaries of interpretation. The book is written, therefore, in the interest not of historical but of exegetical grammar, not of philology as such, but of philology as an auxiliary of interpretation. If it has any value for historical grammar, this is incidental. Its main purpose is to contribute to the interpretation of the New Testament by the exposition of the functions of the verb in New Testament Greek, so far as those functions are expressed by the distinctions of mood and tense.
