Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip.…
The duty here intended is a serious and fixed setting of the mind upon that which we hear: a bending of the will to yield unto it: an applying of the heart to it, a placing of the affections upon it, and bringing the whole man into a holy conformity thereunto. Thus it compriseth knowledge of the Word, faith therein, obedience thereto, and all other due respect that may any way concern it (2 Timothy 2:7; Matthew 15:10; Matthew 13:23; Acts 4:4; Acts 16:14). The comparative degree addeth much emphasis, and intendeth a greater care and endeavour about the matter in hand, than in any other thing; as if he had said, More heed is to be given to the gospel than to the law; more to the Son than to any servant; for he speaks of the gospel preached by Christ. It may be here put for the superlative degree, and imply the greatest heed that may possibly be given; and the best care and diligence that can be used. Thus it is said of the Scriptures, "We have a more sure word"; that is, a most sure word (2 Peter 2:19); thus this very word in my text is often put for the superlative degree. As where Paul saith of himself, ,, In labours more abundant, in prisons more frequent," that is, most abundant, most frequent (2 Corinthians 2:23). Hereby as he doth incite them for the future, to make the best use that possibly they can of the gospel that had been preached unto them, so he gives a secret and mild check to their former negligence, implying that they had not given formerly such heed, as they should have done, to so precious a word as had been preached unto them, but had been too careless thereabouts, which he would have them redress for the future.
