Now, it depends what you mean by "Bible code".....Is the thing you refer to something the world loves?(something a secular world would advocate?)....God is very clear in the Word that the world is diametrically OPPOSED to God in every way.
"Yea, let God be true, but every man a liar..." Romans 3:4
"And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God." Romans 12:2
Scripture cannot be any more clear on this. Numerous other Scriptures speak of the world in direct opposition to God. Use the Word of God as a measure of righteousness to anything that man says.
"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness" 2 Timothy 3:16
"For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." Hebrews 4:12
"Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me." John 5:39
Now, while I do not believe it is wrong to read other books(ie: Christian books, other literature).....One must be very careful to TEST it with Scripture....And let the Holy Spirit ascertain things of righteousness....Because God wrote EVERYTHING that he needed to say in the Word of God....I have PERSONALLY found that straying from the Word too much(ie: placing more concern on other books rather than the Word) can sometimes introduce hidden worldly philosophies into my life.....
So the question "The Bible code?" I do not know the circumstances or ideas behind this, so I leave it with you and the Holy Spirit to discern.....God bless!!=)
