When life feels like a blender on puree, or as if it is falling apart, we need those friends who can act as duct tape and help us hold things together. Their words adhear a sense of calm, hope, and the importance of letting Go and letting God handle the things we need to set down.
When we are stuck in a thought pattern, obsessing or worrying about something over which we have no control, or paralyzed by fear, we need WD-40 friends. Their words seep into our "stuckness", freeing us to let Go and let God's grace move us.
I give thanks for having both! I have them in the many "circles" (or friend's wheel).
In fact tonight, I got to speak to one on the phone, and see several in person.
Proverbs 27:17 - "Iron sharpens iron, so as one person sharpens another".
I think if duct tape and WD-40 were around 2000+ years ago, they would be included in a passage such as this, as well.
