When I was growing up, I was taught to understand the daily Christian life as “walking by the Spirit” (cf. Gal. 5:16). What that meant until perhaps ten years ago (and still means at times of high stress and low coping) was that there was some exactly right plan in God’s head, and I was anxiously trying not to fail it.
Things which aren’t psychologically healthy are never spiritually healthy.
They’re not theologically accurate either: that vision of God and God’s plan had nothing to do with Jesus or the Spirit of Jesus Christ (as the Holy Spirit is repeatedly named in Scripture).
Thomas Merton puts this all so well (from “Renunciation and Contemplation,” quoted in Fr. Albert Haase, Swimming in the Sun, pp. 123-124):
“Your vocation isn’t something that’s in a filing cabinet in Heaven that is kept secret from you and then sort of whipped out at the Last Judgment and [God says], ‘You missed, buddy! You didn’t guess right.’ But your vocation, or anything in life, is an invitation on the part of God which you’re not supposed to guess and you’re not supposed to figure out. It’s something you work out by free response.”
I still think “walk by the Spirit” is a decent, short description of the daily Christian life. But now I want to offer a bigger picture: “walk by the Spirit” when the Spirit is experienced through the whole Biblical canon; in community with other Christians, living and dead (the Tradition); via the Sacraments; and in lived experience, both my personal experience and in connection with the larger human experience.
