“That which is born of the Spirit is spirit” (John 3:6). We should put John 4:24, 6:63, and 3:6 together: “God is Spirit,” “The words which I have spoken…are spirit,” and “That which is born of the Spirit is spirit.” The words in the Bible are spirit. The life which a man receives at the time of regeneration is spirit, and it takes a man with a spirit to read the words of spirit. Only then will the Bible shine within him, and only then will it become useful to him. No matter how clever and well educated a man is, as long as he is not regenerated, this book is a mystery to him. A regenerated person may not be that cultivated, but he is more qualified to read the Bible than an unregenerated college professor. The former has a regenerated spirit, while the latter does not have such a spirit. The Bible is not understood by talent, research, or intelligence. Since God’s word is spirit, only a man with a regenerated spirit can understand it. The root, the very nature, of the Bible is spiritual. If a man does not have a regenerated spirit, he cannot understand this book; it will be a closed book to him.
