The discovery of DNA gives us understanding of what the psalmist calls “God’s Book.” The psalmist is not referring to the Bible as God’s Book, although the Bible is the book that reveals God to all humankind. Even though King David, who wrote Psalm 139, did not know the modern words “DNA,” that is what He was talking about.
Psalm 139 reveals our identity. In Psalm 139:13-18, the psalmist tells us 3 profound things about our lives: First, God alone is the source of each person’s life. Parents are of course instrumental, but it is God alone who gives life. (verse 13) Second, God created each of the 7.6 billion persons in the world as a unique being, unlike any other person. (“I praise You, for I am fearfully and wonderfully made!” (verse 14) Third, God’s thoughts of me are so vast that no book could contain them all. His plan for each life is great, good and perfect. (verses 17-18)
God is the Author of our biological code. DNA is the biological code for every facet of our spiritual, psychological and physical self; it includes the design of our face, our body, hair, limbs, as well as the personality traits with which we are born. The psalmist says, “In Your Book were written, every one of them, the days that were formed for me, when as yet there was none of them!” (verse 16) DNA is the book God has written for each person, each star in the heavens, every tree and every animal. He even gives a name to every star in the heavens! (Isaiah 40:25-26)
It is time that the artificial war between Christianity and science is called off. Christianity is not incompatible with science; in fact, some of the greatest scientists in history have been, and still are today, men and women of great faith in the Lord Jesus Christ.
