11We have much to say about this, but it is hard to explain, because you are dull of hearing.
12Although by this time you ought to be teachers, you need someone to reteach you the basic principles of God’s word. You need milk, not solid food!
13For everyone who lives on milk is still an infant, inexperienced in the message of righteousness.
14But solid food is for the mature, who by constant use have trained their senses to distinguish good from evil.
— Hebrews 5:11-14
