Richard Price

God is always ready to do us all possible good;
but... there is something to be done by us...
which, if neglected, cannot but deprive us of his protection,
and leave us destitute and unhappy.
Can a man...preserve a constant intercourse between his mind and the first and best of all beings,
without growing like to him and being confirmed in pious gratitude and resignation?
It is one of the justest observations, that what we do not think of is the same to us as if it did not exist.
