2:10 "But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. 11 For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. 12 Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God."
I work with people. I also work with wood when I get the chance. They are quite different. Wood is mostly predictable. Sure it can and will expand and contract a certain amount but for the most part it is what it is. The grain of the wood runs in one direction. It stays where I left it (unless of course amount other person moves it). People are not like wood. Turn around in a store and the person who was right with you a minute ago is gone. The grain of a person can also be unpredictable. What they told you yesterday might be different today. What they liked and wanted yesterday might be different today. Exactly what is going on inside a person is largely unknown to anyone but that person. I have even noticed/learned that some people lie so much that they start to believe their own lies themselves. Give me wood any day over that!
In Isaiah God says His thoughts are not our thoughts. He says the distance and difference between His thoughts and our thoughts is like the heavens above the earth. How could we ever "get inside His head" and comprehend the incomprehensible?
Concepts like eternity and immortality are completely foreign to us. The fact we even consider such possibilities or even have the ideas at all is proof that God exists. There is nothing in our surroundings to suggest anything being eternal. Science is even saying the sun won't last forever.
So man has a level of wisdom. We say that what goes up must come down but even we know that isn't always true. If you can launch something out past the gravitational pull of the earth it won't come back down. This wisdom we have is based on experience and observation. However there is a higher wisdom. God knows things we don't. Of all the things God knows the most amazing to me is love. Love? Absolutely. Love is not something a science lab can measure. It makes no "sense" in many cases. We even say things like "he is a fool for love" or "they are madly in love".
Being a fool or being mad are generally not positive. Love does things that logic never would. Common sense rolls his eyes at love. Humans are lousy at love. We don't even really get it. When we talk about it true love, self-sacrificing love, stops us in our tracks. Who would die for someone else? Why forgive? Why help someone who has hurt you? Why spend your own resources to help someone who has wasted all their own and some of yours too?
Certainly the theory of evolution and the survival of the fittest has no explanation for love. In movies villains exploit the love of the hero for his wife or children as a weakness.
If there were no God love would not exist and while our love is a distant and poor reflection of His it still exists as proof that He is our Father.
When we want to hate His Spirit reveals to us, inside us, a better way. When we want to quit or give up, His love awakens in us fresh resources to keep going. Think about it. Think how different this world would be if God’s Spirit was not in us, leading us, and opening to us the capacity, however imperfect and limited, to see things through His eyes.
Jesus is the wisdom of God made plain. Jesus lived with us yet with God's character. If you want to know what true wisdom and true love are watch Jesus. The Spirit of God is with us now to point to Jesus and say "Did you see that? Did you see how Jesus talked to her? Did you see how Jesus handled that situation? Did you see what Jesus did there? That's wisdom. That's love. Do that. Follow Him."
Does every person hear the Spirit of God? Yes. Does every person listen? No. The more we listen the more we hear and see as He sees. The less we listen the more blind and deaf we become.
"Today if you hear His voice do not harden your heart..."
