(1 Corinthians 2:13-14) “Therefore we teach, not in the way in which philosophy is taught, but in the way that the Spirit teaches us: we teach spiritual things spiritually. An unspiritual person is one who does not accept anything of the Spirit of God he sees it all as nonsense; it is beyond his understanding because it can only be understood by means of the Spirit.”
(1 Corinthians 2:10-16) “These are the very things that God has revealed to us through the Spirit, for the Spirit reaches the depts. Of everything, even the depths of God. After all, the depths of a man can only be known by his own spirit, not by any other man, and in the same way the depths of God can only be known by the Spirit of God. Now instead of the spirit of the world, we have received the Spirit that comes from God, to teach us to understand the gifts that he has given us. Therefore we teach, not in the way in which philosophy is taught, but in the way that the Spirit teaches us: we teach spiritual things spiritually. A spiritual man, on the other hand, is able to judge the value of everything and his own value in not to be judged by other men. As scripture says;’ who can know the mind of the Lord, so who can teach him?’ But we are those who have the mind of Christ.”
(Hebrews 8:7-13) “If that first covenant had been without a fault, there would have been no need for a second one to replace it. And in fact God does find fault with them; he says: See, the days are coming-it is the Lord who speaks-when I will establish a new covenant with the House of Israel and the House of Judah, but not a covenant like the one I made with their ancestors on the day I took them by the hand to bring them out of the land of Egypt. They abandoned that covenant of mine, and so I on my side deserted them. It is the Lord who speaks. No, this is the covenant I will make with the House of Israel when those days arrive-it is the Lord who speaks. I will put my laws into their minds and write them on their hearts. Then I will be their God and they shall be my people. There will be no further need for neighbour to try to teach neighbour, or brother to say to brother, ’Learn to know the Lord’. No, they will all know me, the least no less than the greatest, since I will forgive their iniquities and never call their sins to mind. By speaking of a new covenant, he implies that the first one is already old. Now anything old only gets more antiquated until in the end it disappears.”
Carefully read the preceding verses, you may be able to accept my answer if you have a good understanding of them.
We learn math, language, history, etc., by going to school and having others teach us. We have become so accustomed to learning in this manner that it has been carried over to learning about God. Paul told us we couldn’t learn about Jesus that way.
The spiritual aspect of Christianity has almost gone away. It has become so unusual that when I say Jesus speaks to me, people believe I’m hearing voices and am going out of my mind. When a group of friends asked my brother where I was, he answered, “You mean my crazy brother”. The spiritual part of coming to God is just not accepted by most people.
I believe there are many reasons this happened. The main one at this time I believe is control. People have gone to seminaries of different denominations and are taught to accept that denomination’s point of view. These people are convinced what they learned is the truth. Now if some one through the Spirit of God comes and says differently, this threatens their belief.
