Here the apostle returns to what he had in Heb 5:6 cited out of Psa 110:1-7, concerning the peculiar order of the priesthood of Christ, that is, the order of Melchisedec. And here,

I.He declares he had many things which he could say to them concerning this mysterious person called Melchisedec, whose priesthood was eternal, and therefore the salvation procured thereby should be eternal also. We have a more particular account of this Melchisedec in ch. 7. Some think the things which the apostle means, that were hard to be uttered, were not so much concerning Melchisedec himself as concerning Christ, of whom Melchisedec was the type. And doubtless this apostle had many things to say concerning Christ that were very mysterious, hard to be uttered; there are great mysteries in the person and offices of the Redeemer; Christianity is the great mystery of godliness.

II.He assigns the reason why he did not say all those things concerning Christ, our Melchisedec, that he had to say, and what it was that made it so difficult for him to utter them, namely, the dulness of the Hebrews to whom he wrote: You are dull of hearing. There is a difficulty in the things themselves, and there may be a weakness in the ministers of the gospel to speak clearly about these things; but generally the fault is in the hearers. Dull hearers make the preaching of the gospel a difficult thing, and even many who have some faith are but dull hearers, dull of understanding and slow to believe; the understanding is weak, and does not apprehend these spiritual things; the memory is weak, and does not retain them.

III.He insists upon the faultiness of this infirmity of theirs. It was not a mere natural infirmity, but it was a sinful infirmity, and more in them than others, by reason of the singular advantages they had enjoyed for improving in the knowledge of Christ: For when, for the time, you ought to be teachers, you have need that one teach you again which are the first principles of the oracles of God, Heb 5:12. Here observe,

1.What proficiency might have been reasonably expected from these Hebrews - that they might have been so well instructed in the doctrine of the gospel as to have been teachers of others. Hence learn, (1.) God takes notice of the time and helps we have for gaining scripture-knowledge. (2.) From those to whom much is given much is expected. (3.) Those who have a good understanding in the gospel should be teachers of other, if not in a public, yet in a private station. (4.) None should take upon them to be teachers of others, but those who have made a good improvement in spiritual knowledge themselves.

2.Observe the sad disappointment of those just expectations: You have need that one should teach you again, etc. Here note, (1.) In the oracles of God there are some first principles, plain to be understood and necessary to be learned. (2.) There are also deep and sublime mysteries, which those should search into who have learned the first principles, that so they may stand complete in the whole will of God. (3.) Some persons, instead of going forward in Christian knowledge, forget the very first principles that they had learned long ago; and indeed those that are not improving under the means of grace will be losing. (4.) It is a sin and shame for persons that are men for their age and standing in the church to be children and babes in understanding.

IV.The apostle shows how the various doctrines of the gospel must be dispensed to different persons. There are in the church babes and persons of full age (Heb 5:12-14), and there are in the gospel milk and strong meat. Observe, 1. Those that are babes, unskillful in the word of righteousness, must be fed with milk; they must be entertained with the plainest truths, and these delivered in the plainest manner; there must be line upon line, precept upon precept, here a little, and there a little, Isa 28:10. Christ despises not his babes; he has provided suitable food for them. It is good to be babes in Christ, but not always to continue in that childish state; we should endeavor to pass the infant state; we should always remain in malice children, but in understanding we should grow up to a manly maturity. 2. There is strong meat for those that are of full age, Heb 5:14. The deeper mysteries of religion belong to those that are of a higher class in the school of Christ, who have learned the first principles and well improved them; so that by reason of use they have their senses exercised to discern both good and evil, duty and sin, truth and error. Observe, (1.) There have been always in the Christian state children, young men, and fathers. (2.) Every true Christian, having received a principle of spiritual life from God, stands in need of nourishment to preserve that life. (3.) The word of God is food and nourishment to the life of grace: As new-born babes desire the sincere milk of the word that you may grow thereby. (4.) It is the wisdom of ministers rightly to divide the word of truth, and to give to every one his portion - milk to babes, and strong meat to those of full age. (5.) There are spiritual senses as well as those that are natural. There is a spiritual eye, a spiritual appetite, a spiritual taste; the soul has its sensations as well as the body; these are much depraved and lost by sin, but they are recovered by grace. (6.) It is by use and exercise that these senses are improved, made more quick and strong to taste the sweetness of what is good and true, and the bitterness of what is false and evil. Not only reason and faith, but spiritual sense, will teach men to distinguish between what is pleasing and what is provoking to God, between what is helpful and what is hurtful to our own souls.

But strong meat - The high and sublime doctrines of Christianity; the atonement, justification by faith, the gift of the Holy Ghost, the fullness of Christ dwelling in the souls of men, triumph in and over death, the resurrection of the body, the glorification of both body and soul in the realms of blessedness, and an endless union with Christ in the throne of his glory. This is the strong food which the genuine Christian understands, receives, digests, and by which he grows.

By reason of use - Who, by constant hearing, believing, praying, and obedience, use all the graces of God's Spirit; and, in the faithful use of them, find every one improved, so that they daily grow in grace, and in the knowledge of Jesus Christ our Lord.

Have their senses exercised - The word αισθητηρια signifies the different organs of sense, as the eyes, ears, tongue, and palate, nose, and finger ends, and the nervous surface in general, through which we gain the sensations called seeing, hearing, tasting, smelling, and feeling. These organs of sense, being frequently exercised or employed on a variety of subjects, acquire the power to discern the various objects of sense: viz. all objects of light; difference of sounds; of tastes or savours; of odours or smelling; and of hard, soft, wet, dry, cold, hot, rough, smooth, and all other tangible qualities.

There is something in the soul that answers to all these senses in the body. And as universal nature presents to the other senses their different and appropriate objects, so religion presents to these interior senses the objects which are suited to them. Hence in Scripture we are said, even in spiritual things, to see, hear, taste, smell, and touch or feel. These are the means by which the soul is rendered comfortable, and through which it derives its happiness and perfection.

In the adult Christian these senses are said to be γεγυμνασμενα, exercised, a metaphor taken from the athlete or contenders in the Grecian games, who were wont to employ all their powers, skill, and agility in mock fights, running, wrestling, etc., that they might be the better prepared for the actual contests when they took place. So these employ and improve all their powers, and in using grace get more grace; and thus, being able to discern good from evil, they are in little danger of being imposed on by false doctrine, or by the pretensions of hypocrites; or of being deceived by the subtleties of Satan. They feel that their security depends, under God, on this exercise - on the proper use which they make of the grace already given them by God. Can any reader be so dull as not to understand this?

But strong meat belongeth to them that are of full age,.... Or perfect; see Co1 2:6. This does not intend a perfection of justification; for though some have a greater degree of faith than others, and a clearer discovery of their justification, yet babes in Christ are as perfectly justified as more grown and experienced believers; nor a perfection of sanctification, for there is no perfection of holiness but in Christ; and though the work of sanctification may be in greater perfection in one saint than in another, yet all are imperfect in this life; and as to a perfection of parts, babes have this as well as adult persons: but it designs a perfection of knowledge; for though none are entirely perfect, yet some have arrived to a greater degree of the knowledge of Gospel mysteries than others, and to these the strong meat of the Gospel belongs; they are capable of understanding the more mysterious parts of the Gospel; of searching into the deep things of God; and of receiving and digesting the more sublime truths of the Christian religion:

even those who by reason of use, have their senses exercised to discern both good and evil; that is, their spiritual senses, the internal senses of the understanding and judgment, signified by external ones; as by seeing the Son; hearing the voice of Christ; savouring or smelling a sweet odour in the things of God, and Christ; tasting that the Lord is gracious; feeling and handling the word of life, as these are held forth in the everlasting Gospel: and these being exercised on their proper object, by use, an habit is contracted; and such are qualified for discerning, as between moral good and evil, and the worse and better state of the church, and between law and Gospel, so between the doctrines of Christ, and the doctrines of men; who find they differ: the doctrines of Christ such experienced persons find to be good, wholesome, nourishing, and salutary; and the doctrines of men to be evil, to eat, as does a canker, and to be pernicious, poisonous, and damnable; and the discernment they make, and the judgment they form, are not according to the dictates of carnal reason, but according to the Scriptures of truth, and their own experience.

strong meat--"solid food."

them . . . of full age--literally, "perfect": akin to "perfection" (Heb 6:1).

by reason of use--Greek, "habit."

senses--organs of sense.

to discern both good and evil--as a child no longer an infant (Isa 7:16): so able to distinguish between sound and unsound doctrine. The mere child puts into its mouth things hurtful and things nutritious, without discrimination: but not so the adult. Paul again alludes to their tendency not to discriminate, but to be carried about by strange doctrines, in Heb 13:9.
