Interdependency of Scripture

It is perilous to tamper with a chart. Those parts which may be of little importance to one captain may be of the highest importance to another. The chart of the new dispensation does not render unnecessary that of the old. A chart of the Atlantic will not indeed suffice him who is threading the coral reefs of the Pacific Ocean. The authorised chart for those seas must be consulted; but the former chart, in some of its bearings, may be of some use under circumstances; nor will he presume to spread a sail upon the former ocean, in coasting especially, without the chart which belongs to it.—Caughey
