The best antidote against evils of all kinds, against the evil thoughts that haunt the soul, against the needless perplexities which distract the conscience, is to keep hold of the good we have. Impure thoughts will not stand against pure words and prayers and deeds. Little doubts will not avail against great certainties. Fix your affections on things above, and then you will less and less be troubled by the cares, the temptations, the troubles of things on earth.
