From A. E. Knoch

Varying versions and differing doctrines now compel every true lover of God and His holy Word to search the Scriptures in the original. Hitherto this could be done only by Greek scholars. Now it is easy for all who know English. A safe, simple system enables everyone to go past the opinions and traditions of men right back to the inspired writings. Why untangle discordant versions by means of laborious helps and constant corrections, when the mere use of a concordant version will give far greater results with much less effort? This is what students of the Scriptures have always needed, a method of transferring God's thoughts into English, down to the most minute particulars, uniformly, consistently, by a system conforming to the fundamental laws of language. Other translations are filtered through human minds that do not even claim to comprehend what they translate. The Concordant is the only version which recognizes and bridges human fallibility and translates beyond the compiler's knowledge. Others never could escape the bias of the man or men who did the work. This version is bound to be better than the best human interpretation. It seems unbelievable until you understand the method and realize the results. Read it! Revel in it!
