God's truth is absolute. It is not dependent on circumstances. Absolute truth exists in a state of absolute for all eternity past, present and future. First century truth remains the same truth in the twenty-first century. For example, to say that one is alive may be true, but it is not absolute truth because certain parts of one's body, such as the spleen, may not be fully alive, and one may not remain alive for all eternity.
Not every statement in the Bible fits this definition of absolute truth. Some statements are based in opinion and the writers are quick to so indicate. Nor does every truth apply to everyone. Some truths relate only to Israel in the context of their specific covenant with God. Other truths relate only to the church, and others to the church, to Israel, and to every believer. Nevertheless, if a statement fits within the definition of absolute truth, it is true for all time.
Anyone who purports to interpret or reveal God's truth must have two important qualifications. They must have God's indwelling Holy Spirit as evidenced by an occupied (not empty) solar plexus. God's Holy Spirit, not the human brain, reveals and interprets God's truth, and they cannot do so effectively if they lack the indwelling Holy Spirit. They also must have heard directly from the Holy Spirit in connection with the truth that is interpreted or revealed.
Your life depends on your ability to authenticate the sources of doctrine and other information. If you don't know the difference between truth and falsehood you are doomed for all eternity.
