Question: "Is the Bible relevant for today?"
Answer: Hebrews 4:12 says, "For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart." While the Bible was completed approximately 1900 years ago, its accuracy and relevance for today remain unchanged. The Bible is the sole objective source of all the revelation God has given us about Himself and His plan for humanity.
The Bible contains a great deal of information about the natural world that has been confirmed by scientific observations and research. Some of these passages include Leviticus 17:11; Ecclesiastes 1:6-7; Job 36:27-29; Psalm 102:25-27 and Colossians 1:16-17. As the Bible's story of God's redemptive plan for humanity unfolds, many different characters are vividly described. In those descriptions, the Bible provides a great deal of information about human behavior and tendencies. Our own day-to-day experience shows us that this information is more accurate and descriptive of the human condition than any psychology textbook. Many historical facts recorded in the Bible have been confirmed by extra-biblical sources. Historical research often shows a great deal of agreement between biblical accounts and extra-biblical accounts of the same events.
However, the Bible is not a history book, a psychology text, or a scientific journal. The Bible is the description God gave us about who He is, and His desires and plans for humanity. The most significant component of this revelation is the story of our separation from God by sin and God's provision for restoration of fellowship through the sacrifice of His Son, Jesus Christ, on the cross. Our need for redemption does not change. Neither does God's desire to reconcile us to Himself.
The Bible contains a great deal of accurate and relevant information. The Bible's most important message—redemption—is universally and perpetually applicable to humanity. God's Word will never be outdated, superseded, or improved upon. Cultures change, laws change, generations come and go, but the Word of God is as relevant today as it was when it was first written. Not all of Scripture necessarily applies explicitly to us today, but all Scriptures contain truth that we can, and should, apply to our lives today.
