Wuest is a decent language resource addition to any serious Bible student's library. The material is accessible and well organized, and offers a wealth of insight into the meanings behind a large number of Koine Greek words found in the New Testament. His personal translation of the Gospels and Epistles is useful for comparative purposes with those of Moffatt, Goodspeed, Phillips, Murdock, Nicoll, Wesley, Robertson, Westcott & Hort, and others.
Only minor issues: Those who can't read the original Greek will find the use of transliteration helpful but those who can may find this same feature annoying. While there is a Scripture index in Volume III the addition of a Word index would've been a handy inclusion.
