<p>5:13 <i>For everyone that partakes of milk is without experience of the word of righteousness, for he is a babe</i>- It's evident to me, from the very way the Bible is written, that an understanding of the deeper parts depends upon a correct understanding of the basic doctrines. The milk of the word leads on to the meat; Heb. 5:13,14 implies you can only understand the meat if for some time you have been properly feeding on the milk. This means that those who don't understand the basic doctrines of the true Gospel can't really understand the meat of the word. But &quot;the word of righteousness&quot; speaks specifically of the Gospel of imputed righteousness through faith in Christ, by grace and not legal obedience. The Hebrews had not personally experienced that, they had perhaps never fully believed it, and so they needed to be fed with that &quot;milk&quot; of the basic Gospel until they accepted it.</p>
