What the Bible says about Human Spirit Helps understand Material Things
(From Forerunner Commentary)
In verse 11, Paul explains the Spirit's work in us by an analogy. Just as the human spirit enables us to understand material things (Job 32:8), God's Spirit works on a similar but higher plane, allowing us to grasp spiritual matters, specifically, "that we might know the things that have been freely given to us by God" (I Corinthians 2:12)—the benefits of doing God's will, as Romans 12:2 suggests. Of course, this spiritual insight sets us apart from people in the world, so we should not expect them to understand either our doctrines or practices. Frankly, Paul says, it is beyond them.
