Hebrews 5:12 You have been believers so long now that you ought to be teaching others. Instead, you need someone to teach you again the basic things about God’s word. You are like babies who need milk and cannot eat solid food.
As parents, my wife and I have the exciting opportunity to watch our daughter grow. We made a growth chart where we can visibly see how much she has grown over the years. It is exciting for her and us to watch the marks get higher and higher.
But can you imagine how shocked and concerned we would be if, instead of growing up our daughter had shrunk! We would schedule an immediate doctor’s appointment to find out what was wrong. Growth is normal and causes joy – shrinkage would be crazy and cause for alarm.
Many of the Hebrews that this letter is written to have been backsliding in their faith. They are shrinking – the author notices this and raises the alarms. He states that they are back needing the milk instead of solid food. Imagine if a teenager or adult gave up solid food for formula and pureed fruits and veggies. For some reason this seems silly but for some reason long time Christians acting like new believers does not get the same reaction.
Instead of helping others with their faith – these believers still need someone to teach them the basics again. The author wants to go deeper but fears it will go over their heads. So before he dives in to that subject, he issues a strong warning – saying, “GROW UP! You have probably been in a situation where an adult was acting like a child. You want to shout, “act your age” or “grow up.” And essentially that is what the author of Hebrews does with these Hebrew Christians.
In vs. 11 he calls them spiritually dull and they don’t seem to listen. But they didn’t used to be this way. The language used here indicates that there was a drop off – as if they were sick and lacking energy or possibly it is a spiritual laziness. We notice an opportunity to get into God’s word but instead flip on the tv or have a free Sunday morning to go to church but instead decide to sleep in.
