Do we really understand the cost of the "balm of mercy"?
Those receiving mercy (and we all do), do not like to consider the cost of this balm. Some are even totally unaware it has been applied. Most of the rest of us are keenly aware that we do not deserve such grace and kindness, yet even we canot count the cost fully. After all, we've not paid for it. It is as if our healing process involves a certain forgetfulness of the depth of the agony from which we have been rescued from.
It is only possible to count the cost of mercy if you yourself are merciful. And if you are truly merciful be prepared to have your heart pierced by swords, your skin lacerated by malicious men, your body weakened by the toil of love and your intellect pummelled and derided... and be prepared to weep.
And if the "balm of mercy" has been applied, then isn't this the least we can do in return?
