12 And though by this time it would be right for you to be teachers, you still have need of someone to give you teaching about the first simple rules of God's revelation; you have become like babies who have need of milk, and not of solid food. 13 For everyone who takes milk is without experience of the word of righteousness: he is a child. 14 But solid food is for men of full growth, even for those whose senses are trained by use to see what is good and what is 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.
