A work of absolute necessity – Thomas Brooks

Private prayer is a work of absolute necessity,
for the bringing of the heart into a holy frame,
for the keeping of the heart in a holy frame,
for the discovery of sin,
for the preventing of sin,
for the embittering of sin,
for the weakening of sin,
for the purging away of sin,
for a full exercise of grace,
for an eminent increase of grace
to arm us against temptations, afflictions, and sufferings,
to fit us for all other duties and services.
