Hebrews 5:11

11.He therefore makes a preface by saying that he had many things to say, but that they were to prepare themselves lest these things should be said in vain. He reminds them that they were hard or difficult things; not indeed to repel them, but to stimulate them to greater attention. For as things that are easily understood render us slothful, so we become more keenly bent on hearing when anything obscure is set before us. He however states that the cause of the difficulty was not in the subject but in themselves. And indeed the Lord speaks to us so clearly and without any obscurity, that his word is rightly called our light; but its brightness become dim through our darkness. (91) This happens partly through our dullness and partly through our sloth; for though we are very dull to understand the truth of God, yet there is to be added to this vice the depravity of our affections, for we apply our minds to vanity rather than to God’s truth. We are also continually impeded either by our perverseness, or by the cares of the world, or by the lusts of our flesh. Of whom does not refer to Christ, but to Melchisedec; yet he is not referred to as a private man, but as the type of Christ, and in a manner personating him.
