God is always precise, because you don't comprehend His precision doesn't negate it, it just means you don't comprehend it.
The so-called "Biblic-codes" are nothing more than a fraud, and anyone who believes that fraud is deceived and lacking in discernment.
Perhaps some day I'll bother to provide you with a list of Scriptural prophecies which were/are far from precise.
Your statement on the Bible Codes makes clear you have either not read the latest research or do not comprehend it or have such fierce closed-minded biases on it that no facts would enlighten you.
The Bible Codes pass CHRIST'S OWN STANDARD CRITERIA FOR DISCERNING SPIRITS in that they declare the basic doctrines of the faith about Christ coming in the flesh, being Lord of Lords and King of Kings etc. If you wish to argue with Christ Himself on such matters, help yourself. But I wouldn't recommend it.
