Because of a failure to understand God’s purposes as outlined in the Scriptures some have felt it necessary to alter many of the plainest statements of Holy Writ. Supposing that God could not have meant exactly what He said, they have concluded that these things must be interpreted in a “spiritual” sense.
Actually there is nothing spiritual about failing to take God at His Word, and seeking to explain away difficulties by arbitrarily altering what He has plainly said.
First, this would leave us at the mercy of theologians. If the Scriptures do not mean what they say, who has the authority to decide what they do mean? And how can we turn to the Word of God for light if it does not mean what it says, and only trained theologians can tell us what it does mean?
Second, this altering of the Scriptures affects the veracity of God. If the obvious, natural meaning of the Old Testament promises are not to be depended upon, how can we depend upon any promise of God? Then, when He says: “Whosoever shall call upon the name of the Lord shall be saved” (Rom. 10:13), He may also mean something else instead of what He actually says.
Third, this “spiritualizing” of Scriptures endorses apostasy, for it allows men to alter the meaning of God’s Word according to their will.
The path to a true understanding and enjoyment of the Bible is not in altering but in “rightly dividing” it (II Tim. 2:15).
Those who have resorted to the “spiritualization” of the prophetic Scriptures because they cannot account for the seeming cessation in their fulfillment, will find the solution to their problem in a recognition of the unique character of Paul’s apostleship and message. Recognize “the mystery” revealed through Paul and there will be no need to alter prophecy. source
[…] The Word of God stands alone as the final authority in all matters of faith and practice. It does not need the assistance of concepts, which only serve to undermine the Scriptures. There is one true and living God whose name is Jesus Christ, “For in Him dwelleth all the fullness of the Godhead bodily” (Col. 2:9). All other gods or views of gods are false! source […]
