Those are in fundamental agreement who, without any reservation, submit to the Word of God. When the Word of God has spoken in any matter, that matter is settled. There may be things that some men have not yet found in their study of the Bible; there may be matters with reference to which they have accustomed themselves to an inadequate mode of expression; yet, no matter what their deficiency may be, they are determined to accept the Bible doctrine. Where such is the case, there is fundamental agreement…. A fundamental agreement is all the church can ever hope to attain here on earth. We are not all equally gifted; one has a much clearer and a much more comprehensive insight into God’s doctrines than another. We all strive to grow daily in understanding. Besides, when once we have accustomed ourselves to a faulty or an inadequate expression, it is not only difficult to unlearn the particular phrase and to acquire a proper one, but the inadequate term may tend also to warp our views on other points. Yet, in spite of all such differences, where there is an unconditional willingness to hear what God has to say in his Word, there is fundamental agreement.
