Each Sin Has Its Door.

'Each sin has its door of entrance.
Keep-that-door-closed!
Bolt it tight!
Just outside,
the wild beast crouches
in the night.
Pin the bolt with prayer;
God will fix it there.'

(from "Listening to the Indwelling Presence,"
compiled by a Religious, Pellegrini, Australia, 1940, p.191)
