Note the emphasis on self and on doing. But the gospel is not about what we do for God, it's all about what he has already done for us. Without the cross, the commands are just rules that lead to self-rightous moralising if we are not careful.
But there's a twist in the story in the form of the missing questions. This expert never asks about loving God. Surely that's the big question. How do I love God with all my heart, soul, strength and mind?
I wondered yesterday if we too focus out attention on the limit of our grace towards others in order to avoid asking the difficult questions about our life with God.
