This book is not a commentary, but offers itself as a supplement to the commentaries. Every student of the New Testament has general helps that shed an impartial, even if sometimes needless, light on every chapter. But in this age of books, when much of the reader's time is take up in selecting what to read, it is but fair that the exegetical writer should select beforehand, and offer only what seems to him not found already in the necessarily common material of complete works. If he thinks that he has gained new light on various passages, let him be content to tell what has come to him here and there. Let him resolutely refrain from making a commentary. Otherwise what is really new and good in his work will be overlaid and hidden, or at least crowded and cramped, by what may be good but cannot be new. I have tried, in this little volume to follow the advice now given.
