Hebrews 5:13 means that a believer who still needs only the simplest basics of faith has not yet grown into skill at understanding and living out God’s righteous ways. The writer is describing spiritual immaturity as a stage of development that is meant to be left behind, not a permanent condition. The words come from an unnamed author writing to a Jewish Christian congregation that had grown slow to learn and was still stuck on elementary teaching.
For everyone who lives on milk is not experienced in the word of righteousness, for he is a baby.

What Hebrews 5:13 Means
The verse uses the picture of milk, the food of infants, to describe basic instruction in the faith. Someone who “lives on milk” is someone who only ever receives the first lessons and never moves on to anything heavier. The writer is not scolding them for being new. He is pointing out that they have been believers long enough that they should now be teaching others, yet they still need the basics taught to them.
The phrase “not experienced in the word of righteousness” describes a person who has not practiced living by God’s standards of right and wrong. Experience here means something gained by repeated use, the way a musician becomes skilled through many hours at the instrument. The verse ends by calling such a person “a baby,” a plain image of someone who has not yet developed the strength and judgment of an adult.
The verse does not promise that every believer will become an expert in Scripture, and it does not say that milk is a bad thing. It names a gap between what someone has been given and what they have actually learned to use. The remedy is steady growth through practice, which the writer goes on to describe in the next verse.
The Context of Hebrews 5:13
Hebrews is a letter addressed to Christians who were facing pressure, and the author is careful, sometimes sharply so, in calling them forward. The surrounding verses speak of Jesus as a high priest in the order of Melchizedek, a teaching the writer says is hard to explain because his readers have become dull of hearing. The milk-and-solid-food image is part of his effort to show them that they have been stuck in the nursery when they should be ready for deeper truths.
Read in that setting, the verse is an invitation rather than a rebuke alone. Verse 14 completes the thought by saying solid food belongs to those who are full grown, whose senses have been trained by use to tell good from evil. So the writer is describing a path: milk for beginners, then solid food for those who have practiced. The verse makes most sense when you see that the author expects his readers to move forward.

Paul writes about believers no longer being children, tossed about by every wind of teaching. The verse shows that growth in understanding protects us from being easily misled, which is a practical reason the writer of Hebrews wanted his readers to mature.
A Short Prayer From Hebrews 5:13
Lord, you have given me your truth, and I thank you for the basic lessons that first taught me who you are. I confess that I have often been content to stay with what is familiar and avoid the harder work of practicing what I know. Teach me to grow up in faith, to apply your righteous ways in my daily choices and to become someone who can help others. Train my senses to tell good from evil, and give me patience for the steady work of becoming mature in you. Amen.
