You are not ready for more advanced spiritual truth.

Hebrews 5:11-14

11 Although there is much to say to you(pl) about how Christ resembles Melchizedek, this is hard for me to explain to you because you now understand things so slowly. 12 You became Christians long ago. So by now you should be teaching spiritual truths to others. But you still need someone to teach you again the truths that God has revealed. I am talking about the truths that we teach people when they first believe in Christ. You need those elementary truths like babies need milk [MET]. You are not ready for advanced teaching, which is like the solid food which mature people need [MET]. 13 Remember that those who are still learning these elementary truths [MET] have not become familiar with what God says concerning becoming/being righteous. They are just like [MET] babies who need milk! 14 But the more advanced spiritual truth is for people who are spiritually mature, just like [MET] solid food is for people who are physically mature. They can tell the difference between what is good and what is evil, because they have trained themselves to keep doing that.
