The doctrines herein treated are dealt with from the standpoint of Biblical rather than Dogmatic theology. This is evident from the plan which is followed in the work, namely, to gather together all the Scripture passages dealing with the subject under consideration, and then seek to understand the meaning of these references by the study of the text itself as well as its context and parallel passages; and finally, from the selected proof-texts, formulate the doctrinal teaching, and place such results under appropriate headings.
