I learned this little nugget from Bob Thune.
Transparency is NOT vulnerability.
Glass is transparent but does not invite you in.
Glass is a barrier.
Vulnerability is being transparent and opening a door of invitation into your confessor's quarters.
We must be more than simply confessional.
We must be willing to be corrected after confessing.
We must be willing to hear how the Gospel addresses our depravity.
We must want more than simply to be an object of sympathy.
We must want sanctification.
We must be more than simply transparent, we must be vulnerable.
That is, IF we want to change.
If we only want to be good, dutiful Christians; transparent windows and closed doors will suffice.
