12 For when by reason of the time you ought to be teachers, you again need to have someone teach you the rudiments of the first principles of the oracles of God. You have come to need milk, and not solid food. 13 For everyone who lives on milk is not experienced in the word of righteousness, for he is a baby. 14 But solid food is for those who are full grown, who by reason of use have their senses exercised to discern 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.
