How do we measure our love of God?

God wishes to be served
to the last breath, to the exhaustion of the last drop of strength,
and He multiplies our capacities for suffering and doing
so that our dedication may reach the extreme limit
of the unforeseeable, the improbable, the miraculous.
The measure of the love of God is
to love Him without measure, said Saint Francis de Sales.
The measure of fighting for God consists
in fighting without measure, it may be said.

Plinio Corrêa de Oliveira
