That in the beginning of the spiritual life, we ought to be faithful in doing our duty and denying ourselves; but after that, unspeakable pleasures followed. That in difficulties we need only have recourse to Jesus Christ, and beg His grace; with which everything became easy.
That many do not advance in the Christian progress, because they stick in penances and particular exercises, while they neglect the love of God, which is the end. That this appeared plainly by their works, and was the reason why we see so little solid virtue.
That there needed neither art nor science for going to God, but only a heart resolutely determined to apply itself to nothing but Him, or for His sake, and to love Him only.
