12 For when for the time ye ought to be teachers, ye have again need that [one] should teach you what [are] the elements of the beginning of the oracles of God, and are become such as have need of milk, [and] not of solid food. 13 For every one that partakes of milk [is] unskilled in the word of righteousness, for he is a babe; 14 but solid food belongs to full-grown men, who, on account of habit, have their senses exercised for distinguishing both good and evil.

Matthew Henry's Commentary on Hebrews 5:12-14

Commentary on Hebrews 5:11-14

(Read Hebrews 5:11-14)

Dull hearers make the preaching of the gospel difficult, and even those who have some faith may be dull hearers, and slow to believe. Much is looked for from those to whom much is given. To be unskilful, denotes want of experience in the things of the gospel. Christian experience is a spiritual sense, taste, or relish of the goodness, sweetness, and excellence of the truths of the gospel. And no tongue can express the satisfaction which the soul receives, from a sense of Divine goodness, grace, and love to it in Christ.
