Although neuroscience has made great progress in understanding how the brain works, scientist admit they’re still in the early stages of understanding it. They understand brain architecture, some aspects of its function, and regions that respond to environment, activate our senses, and generate movements and contain emotions. But they still can’t figure out how all these interactions contribute to behavior, perception, and memory. God’s incredibly complex, created masterpiece—humanity—is still mysterious. David acknowledged the marvels of the human body. Using figurative language, he celebrated God’s power, evidenced by His sovereign control over the entire natural process of humans “being knit . . . together in [his] mother’s womb” (Psalm 139:13). He wrote, “I am fearfully and wonderfully made; your works are wonderful” (v. 14). The ancients viewed the development of a child inside the mother’s womb as a great mystery (see Ecclesiastes 11:5). Even with limited knowledge of the marvelous complexities of the human body, David still stood in awe and wonder of God’s amazing work and presence (Psalm 139:17-18). The marvelous and wonderful complexity of the human body reflects the power and sovereignty of our great God. Our only responses can be praise, awe, and wonder!
