Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip. Hebrews 2:1
There are men in our day who have studied the Bible and come to the conclusion that since God is vocal in His universe, there is no such thing as an inspired canon of Scripture containing a full body of revealed truth that can serve as the one final source of doctrine and practice.
These teachers reason that if God is still speaking, then we must keep our minds open to further revelation given, it may be, through poets, philosophers, scientists and religionists of various kinds. They would insist that wherever new truth is discovered or new and advanced ideas are brought forth, there God is speaking again as He once spoke by the prophet and seer in olden times.
While we grant such men the right to believe what they will, this one thing is settled: whoever, for whatever reason, denies the finality of the biblical revelation and insists upon a continuing revelation having the same authority as the sacred Scriptures has shut himself out from the name of Christian! He is simply not a Christian in the scriptural and historic meaning of the word.
Between the ideas of a fixed biblical canon and a constantly speaking God there is no contradiction! The point I make is that if the living voice of God were not speaking in the world and in the hearts of men the written Word could have no real meaning for us.
