All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
That the man of God may be perfect, throughly furnished unto all good works. (2 Timothy 3:16-17)
"In interpreting the Scriptures, the Old and the New Testaments must be shewn to agree with one another.
If I were to put an interpretation upon the Old which did not harmonize with the New,
that interpretation would not be correct. And if I were to put an interpretation upon the New,
which did not agree with the Old, that interpretation would not be correct.
Hence then, you perceive that no teaching is to be extracted
from one passage of Scripture no matter where that passage may be which cannot be fully sustained
by the Scriptures as a whole.
Some people say that you can prove anything from the Scriptures, but that is not correct.
You can only prove one thing from the Scriptures, and that thing is the truth."
Key to the Understanding of the Scriptures
The key to the understanding of the Bible is of a unique character. It is easily obtained, yet few possess it; it reveals the way of life eternal, yet few desire it; it is within the grasp of all to find, yet few seek it. The key to the understanding of the Bible, can become the possession of men and women of character. It requires of them a determination to investigate the Gospel message, and embrace it. It calls upon them to reject preconceived ideas about salvation, and with independence of mind, ponder the principles of Divine revelation.
The Key Lost by Religious Leaders
“Woe unto you lawyers! For ye have taken away the key of knowledge: ye entered not in yourself, and them that were entering in ye hindered” (Luke 11:52).
In these words, Christ condemned the cold, formalized religion of his day, as being both repulsive and destructive. The leaders had rejected the crystal-clear teaching of Truth, and had dispensed with the key to knowledge. Worse, by their false teachings, they “prevented” others, from using it, who might otherwise have benefited by the knowledge of Truth. Christ urged his hearers to avoid such an influence (Matt. 23:30).
