HEB 5:12

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].
