Sadly, churches are filled with spiritually stunted babies who cling to their routines & who throw fits when someone dares to challenge the statues quo. Why are these people stunted in their growth? Here's a possible answer:
We Still Can't Feed Ourselves.
It's funny to watch a little kid try to feed themselves. They get as much food on them as in them. It's cute when they're learning how to manipulate a fork or spoon to get the food to their mouth, but it's not so cute when all of this happens & a few minutes after the meal, the child is complaining because he or she is hungry. For most kids there is a stage where they should be able to feed themselves, & if they can't, something is wrong.
Spiritual babies are not that different. They either don't know how or refuse to feed themselves spiritually. Often they assume that it's someone else's job to feed them. Their Bibles become props used to decorate their homes or as an accessory each Sunday at church. In some cases, their Bible doesn't even get that much attention. Having served in ministry in one way or another for 20 years, I'm still shocked at how often I see people, especially men, come to worship or Bible study without a Bible. I mean surely you think you're going to need & use your Bible at church, right?
As a result, they get just enough of God's Word into their lives to make a mess. They often talk about the Bible, but they don't really know Scripture or use it as the filter for their worldview. That's why it's not uncommon for spiritually stunted babies to be self-righteous hypocrites who hold people to standards of "holiness" that aren't even biblical. Each Sunday they climb into their high-chairs, known as a pew, & demand to be fed by the pastor or their small group leader. If you want a picture of a spiritually stunted baby, go check out the Pharisees in the Gospels. They embody the idea of spiritually stunted.
Believers who can't feed themselves will not be healthy believers, & it will affect the rest of the family (church.)
