When I told my young daughter that a 3-month-old baby boy was coming to our house for a visit, she was delighted. With a child’s sense of hospitality, she suggested that we share some of our food with the baby; she thought he might enjoy a juicy orange from the bowl on our kitchen counter. I explained that the baby could drink only milk, but that he might like oranges when he was older.

The Bible uses a similar concept to describe a believer’s need for spiritual food. The basic truths of Scripture are like milk—they help new Christians thrive and grow (1 Peter 2:2-3). In contrast, “Solid food belongs to those who are of full age” (Heb. 5:14). Believers who have had time to digest and understand the basics can move on to investigate other biblical concepts and begin to teach others these truths. The rewards of spiritual maturity are discernment (v.14), godly wisdom (1 Cor. 2:6), and the ability to communicate God’s truth to others (Heb. 5:12).

Like a loving parent, God wants us to grow spiritually. He knows that feeding only on spiritual milk is not in our best interest. He wants us to move on so we can enjoy the taste of solid food.
