This is a picture of my husband, Trevor, walking the slackline.
It’s basically a horizontal bungee cord, upon which he somehow maintains some semblance of balance in spite of the fact that it bends and sways in response to the slightest breeze, much less his weight or movement!
People see him walking on it in the park, and either assume they could never do it, or that it’s easy.
But it’s actually neither. Most people (although sadly not me) could walk a slackline if they were willing to put in enough time and dedication and willingness-to-fall-off effort. Trevor spent weeks just trying to stand up on it, and then months more mastering the art of walking, turning, crouching and walking backwards on it. And there are others that have taken the art to the level of impressive, and can even do tricks on the slackline or cross deep canyons on a high rope!
And I think that slacklining is a useful metaphor for us as we think about what it means to begin to live life over our centre.
