Sorrow is good for nothing but sin. If you shed tears for outward losses, it will not advantage you. Water for the garden, if poured in the sink, does no good. Powder for the eye, if applied to the arm, is of no benefit. Sorrow is medicinal for the soul, but if you apply it to worldly things it does no good. Oh that our tears may run in the right channel and our hearts burst with sorrow for sin!
– Thomas Watson –
