Hebrews 5:12-14

ISV(i) 12 In fact, though by now you should be teachers, you still need someone to teach you the basic truths of God’s word. You have become people who need milk instead of solid food. 13 For everyone who lives on milk is still a baby and does not yet know the difference between right and wrong. 14 But solid food is for mature people, whose minds are trained by practice to distinguish good from evil.
