For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food. (Hebrews 5:12)
The Christians to whom this letter has been addressed are by no means like the baby Christians of Corinth. Nevertheless, they are still in the early stages of their walk with Christ. They have gone beyond being spoon fed and can eat on their own. They have learned how to walk in the ways of a witness. They are able to speak in Christian clichés. They know their rightful names in Christ. They know the biblical address of a few famous scriptures.
The problem is that they have been at this same basic level for a very long time. The writer says that they have been Christians long enough that by now, they should be teachers and yet they are still at an elementary level of the faith. Their growth has become stagnant and their walk with Christ has become repetitive and monotonous. We all know Christians who have been in the Lord and in the church for ages and still have only reached minimum levels of knowledge, understanding and growth.
Hebrew’s solution for those who may be stuck at this level is for them to re-examine afresh the first and fundamental principles of the oracles (word) of God. Then, after that, start again to lay the foundation for further growth.
There is absolutely nothing wrong with being in the kindergarten. The trouble comes when you are 15 years old and still in the kindergarten. Maybe, it is time to move on up a little higher.
