We have much to say about this, but it is hard to make it clear to you because you no longer try to understand. In fact, though by this time you ought to be teachers, you need someone to teach you the elementary truths of God’s word all over again. You need milk, not solid food! Anyone who lives on milk, being still an infant, is not acquainted with the teaching about righteousness. But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil.

--Parallel verses:
‭‭Psalms‬ ‭119‬:‭10‬-‭11‬
I seek you with all my heart; do not let me stray from your commands. I have hidden your word in my heart that I might not sin against you.‭‭

Proverbs‬ ‭3‬:‭3‬
Let love and faithfulness never leave you; bind them around your neck, write them on the tablet of your heart.

Immaturity in our spiritual lives looks like someone who hears the truth, embraces it, but only does so because everyone else is doing it too. Later, when it is not popular, they turn away.

We are called to live for more than just a milk-toast faith. God wants our faith to be vibrant and strong. He wants us to eat spiritual beef. Here the writer of Hebrews is asking the Jewish Christians in the Church: “Where’s the beef?” And he is just as disgusted as the old lady on the Wendy’s commercials to find not much of it. We must chew on his Word and digest it like solid food.

When I hide God’s word in my heart, it means I have sought to keep its commands and treated them like a treasure map to live by. I have internalized God. In binding love and faithfulness around my neck, I am taking them with me and never letting them out of my site.

Lord, help me not to be satisfied with milk only, the food of infants. Give me the motivation and desire to eat solid food spiritually — spiritual steak. Then I will be able to understand your heart and follow you in your ways.
