Many struggle with the idea that only people who have the Bible can know that God exists. I believe you can agree with me that man is finite, and God is infinite. If man is to know God, then it must come about by God taking the initiative in making himself known. This communication is known as revelation. The Bible describes two forms of revelation, namely general and special revelation. According to Psalm 19:1-6 and Romans 1:20, God has revealed truth about himself such as His invisible attributes, His eternal power and Godhead. He did so through his creation and this general revelation is available to us all. These scripture passages teach us that God’s work testifies of Him and His greatness.
In addition to the external revelation of nature, God has also implanted the knowledge of His existence in every human heart. But sadly, many have chosen to suppress this truth, “The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness” (Romans 1:18).
God’s special revelation involves His more direct means of communication to some people in a variety of ways, including dreams, visions, and angels but most clearly in the Person of Christ (Hebrews 1:1-2) and in the pages of Scripture. Special revelation was necessary because man had lost the relationship of favor that they once had prior to the fall. When sin entered the world, the need for special revelation became more critical. Man needed to know God in a fuller way, but general revelation had its limitations.
The Bible was not merely written for our information, but for our transformation. It is the word of God in the form of written Scripture that is “God-breathed” and “useful for teaching, rebuking, correcting and training in righteousness” (2 Timothy 3:16). God chose to reveal himself through His written Word, revealing more truth about His Person and Work. While the Bible is an inspired revelation from the living God, it requires our response before it can have an impact upon our lives. Scripture must move from our head to our heart to accomplish the purpose for which it was given.
In conclusion, the Bible is necessary for knowing the gospel (through which we are saved), for maintain spiritual life, and for knowing God’s will, but is not necessary for knowing that God exists or for knowing something about God’s character and moral laws.
