Only eternal truths are
capable of filling our hearts and of guiding us with assurance....
all we have to do is to rely
strongly and solidly on one of the
perfections of God, e.g.. His goodness, His providence, His truth.
His immensity, etc. We
have only to be firmly established on these
divine foundations in order to become perfect in a short time. It's
not that it isn't also good to
be convinced by strong, significant
reasons, which can always help
us, but they must be subordinate to
the truths of faith. (SV XI, 25)
