Beginners in the service of God sometimes lose confidence when they fall into any fault. When you feel so unworthy a sentiment rising within you, you must lift your heart to God and consider that all your faults, compared with divine goodness, are less than a bit of tattered thread thrown into a sea of fire. Suppose that the whole horizon, as far as you can see from this mountain, were a sea of fire; if we cast into it a bit of tattered thread, it will disappear in an instant. So, when you have committed a fault, humble yourself before God, and cast your fault into the infinite ocean of [love] and at once it will be effaced from your soul; at the same time all distrust will disappear.
–Saint Paul of the Cross (1694-1775)
