12 By this time you ought to be teachers yourselves, yet here I find you need someone to sit down with you and go over the basics on God again, starting from square one - baby's milk, when you should have been on solid food long ago! 13 Milk is for beginners, inexperienced in God's ways; 14 solid food is for the mature, who have some practice in telling right from wrong.
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.
