As the writer has been making his case about the superiority of Jesus to the types and shadows of the Old Covenant he pauses for a moment. It’s as if he sees the readers eyes glossing over. This is not because his material is boring. Quite the contrary, its heady stuff. He’s jumped into the deep end. He wants to develop in them a robust theology, or more precisely “Christology” so that they will be well-prepared for the pressures and persecutions headed their way.
The writer of Hebrews wants us to be prepared. He’s like the faithful drill Sargent who knows the dangers of the battlefield and is determined to prepare his soldiers to survive. So he is hard with them. This is why the writer of Hebrews dishes out rebukes and warnings like disciplinary whacks. He cannot let the church remain weak when the storms come, lest they get swept away.
His message is plain: go on to maturity.
