Truth is not Truth by itself, it is necessary to establish it as such, it is not enough to nod to it, nor is nodding to it the way to establish it. A person may be before the Truth but if he does not establish it for himself, and in his environment, the person continues to live in the lie of ignorance of God.
Truth does not consist of knowledge. Truth is not a cumulus of knowledge, it does not depend on how much we know, even how much of the Bible we know. We can only know one point of the Scriptures, if we live by that one point of the Scriptures, that one point becomes Truth and by it others are affected, some for life, and others for condemnation.
