One of the greatest exegetical conundrums for me is this final phrase in the Lord’s Prayer. My assumption is that when asked how to pray, Jesus would have given an answer that was understandable. But then again, I am not Jesus.
As we all know, Jesus starts by orienting us to God, his immanence and transcendence. “Our Father in heaven.”
We then confess his supremacy in all things: his holiness, kingly rule, divine will. And we conclude by admitting our dependence on him for all things: sustenance, forgiveness, and protection from sin and Satan (assuming τοῦ πονηροῦ is substantival).
