The message of the word was not in them, in their souls. That is the proof.
The same is true today. If you don’t love the Son, and see the Son of God, and depend upon him, you cannot understand the Bible. These theological liberals - well, they scarcely even believe the Bible as inspired - but what can they understand about the Bible? They can pick up their higher degrees, they can become professors of faculties of divinity in various universities that do not believe and honour the Son, but they can’t fit it together because, Christ, the Son, links everything in the Bible, and they reject him. Tragically it is the same with some people who think they are Christians, but they have never come to Christ. This Book is just a muddle to them. They’ll never understand it.
