Sustenance is defined as “food and drink regarded as a source of strength; nourishment; or the maintaining of someone or something in life or existence.”
Jeremiah the prophet described it this way: “Your words were found, and I ate them, and your word was to me the joy and rejoicing of my heart; For I am called by your name, O Lord God of hosts.” (Jeremiah 15:16, NKJV). “As newborn babes, desire the pure milk of the word, that you may grow by it…” (1 Peter 2:2, NKJV) There are several times that the Word of God is described as our spiritual food. It’s an interesting analogy, and one that deserves some thought.
First, it indicates that spiritual growth is a process, not something that happens instantly. You don’t eat all the meals of your life in one sitting, and you don’t absorb the Bible that way either. Peter says that we start as immature spiritual beings, and should begin with “the pure milk” of the word, receiving our sustenance in a form we can handle. It’s an analogy that makes sense. You grow in understanding God’s word as you “eat” it and apply it in your life, and it provides your spiritual sustenance.
Second, look in the mirror at your physical self. Then imagine your spiritual self. If God’s word is your spiritual sustenance, then what kind of shape is your spiritual man in? When you look into your spiritual mirror, who do you see?
I feed my physical body, (usually more than it requires) and I make sure it gets the fuel it needs to grow and stay strong. It’s easy for us to see the results of feeding our physical man. Now, picture your spiritual man (or woman) in your mind’s eye. He’s up there, waiting for nourishment. His needs are the same as or even greater than your physical body’s. But is he or she strong and healthy? How many meals a week are you feeding HIM (or HER)? For most of us, I’d bet that our “spiritual self” is just wasting away, looking like a prison camp refugee, half-starved and emaciated. Our spiritual self is weak and listless, propped over in a corner just waiting for the preacher to spoon-feed them their weekly meal…
If God’s word is our spiritual food, we should be sitting at the banquet table enjoying a feast each day, not waiting for someone else to toss us a crust of bread every once in a while. Think about your poor spiritual body, and consider feeding it a little life-giving nourishment.
Jeremiah says that a couple of things will happen. First, God’s words provide a reason to live with joy and rejoicing in your heart. Not a bad outcome if you’d like a little more JOY in your life! And second, Jeremiah says he was identified with God. He was called by God’s name, which means he was in the family, fully adopted as an heir—another positive result and another reason to rejoice. So eat. Grow. Rejoice. Repeat.
Look into your spiritual mirror. Who is looking back? Are they strong, or is there maybe something that they lack? If the Word of God is food, how often are they eating? Do they get nutrition in the meals that you are feeding? Can you, like Jeremiah, say the Word of God is filling? Do you really want some? You can get it, if you're willing. You can say with him, "Thy Words were found, and I did eat them" And people will sense something godly in you when you meet them. Remember this: the word of God is food, and it is real. Your spiritual man should eat some every day, at every meal.
