I’ve been getting into David Powlison’s book on biblical counselling, Seeing With New Eyes (it is, as they say, an oldy but a goody).
Reflecting on the context of Paul’s exhortation to ‘be filled with the Spirit’ (Ephesians 5.15-20), Powlison says:
To be “filled with the Spirit” is to have your language alive to God, both your daily conversations with others and the inward conversation within your own heart. Your cognitive stream-of-consciousness and your social interactions are meant to be psalm-like and psalm-informed. That includes the ability to quote a psalm in a timely and relevant way, but it is something much more. Paul calls you to a lifestyle of joyous dependence on Christ, to live in faith like the Psalms. (‘Counsel Ephesians’, page 24)
My sense is that letting the Psalms shape our talk (and our self-talk) might protect us from developing an immaculate-looking, Ikea-Catalogue prayer life.
That’s what it’d sound like to be filled with the Spirit.
