What does Hebrews 5:12-14 teach about the difference between milk and solid food?

In Hebrews 5:12-14, the author uses the metaphor of milk and solid food to illustrate the difference between basic teachings of the faith and deeper theological truths. Milk, appropriate for spiritual infants, signifies initial teachings that lay the foundation for faith, while solid food represents advanced doctrine that requires greater understanding and maturity. Believers are encouraged to progress from merely receiving basic nourishment to engaging with and digesting profound truths about Christ. This transition is essential for spiritual growth and enables believers not just to consume but to teach and share their understanding of the Gospel.
