Hebrews 5:12-14

WPNT(i) 12 Really, because although by this time you ought to be teachers, you need someone to teach you the elementary principles of God’s oracles all over again; you have come to the point of needing milk, not solid food! 13 Surely; whoever lives on milk is an infant, and therefore unskilled in the word of righteousness. 14 On the other hand, solid food is for the mature, those who by habitual use have trained their senses to distinguish good from bad.
