Not only has God made an intricate and finely tuned physical world He has also instilled a sense of eternity in the heart of every person (Ecclesiastes 3:11). How complex is the DNA “code” that we carry in every cell of our bodies? Does not the complexity and purpose of DNA argue for an Intelligent Writer of the code?
My assumption would be that there is an intelligent sender of the message, someone who created the code. If I found an encoded message, I would seek out a cryptographer to help break the code. The universe displays great design, and this argues for a Great Designer. Our measurement of time is not based on wristwatches, but on God’s handiwork-the regular rotation of the earth (and the radioactive properties of the cesium-133 atom). But there is far greater design and precision in the world around us. Based on the watch’s design, I would assume it had a designer. If I found a wristwatch in the middle of a field, I would not assume that it just “appeared” out of nowhere or that it had always existed. “The heavens declare the glory of God the skies proclaim the work of his hands.” (Psalm 19:1). “For since the creation of the world God’s invisible qualities-his eternal power and divine nature-have been clearly seen, being understood from what has been made, so that men are without excuse” (Romans 1:20). The most basic proof of God’s existence is simply what He has made. We know that God is real because He has revealed Himself to us in three ways: in creation, in His Word, and in His Son, Jesus Christ.
