The way of man is not always in his own power; but it belongs to God to give and to comfort when He will, and as much as He will, and to whom He will, and as it shall please Him, and no more.
Some, wanting discretion, have ruined themselves upon occasion of the grace of devotion: because they were desirous of doing more than they could, not weighing well the measure of their own weakness, but following rather the inclination of the heart than the dictates of reason. And because they presumtuously undertook greater things than were pleasing to God, there tehy quickly lost His grace.
They became needy, and were left in a wretched condition, who had built themselves a nest in heaven, to the end that being thus humbled and impoverished, they might learn not to trust to their own wings, but to hide themselves under Mine. (Bk 3, ch 7)
O divine Sun! I am happy to feel so small and weak in Thy presence, and my heart is at peace. I know that all the eagles of Heaven take pity on me and protect me from the vultures - the fallen angels - whom I do not fear, as I am not destined to become their prey, but that of the divine Eagle.
O Word of God, my Saviour! as an Eagle Thou didst come down upon this land of exile, there to suffer and die, that Thou mightest carry upwith Thee the souls of men into the very bosom of Love, the Blessed Trinity. The Saints have done great things for Thee in the folly of their love, for they were eagles, but I am too little to attempt great things. and my folly is the hope that I shall become the victim of Thy love; my folly is to count on the intecession of the ANgels and Saints that may fly up to Thee with Thine own wings...
I cherish the hope that one day Thou wilt swoop down upon me and carry me up until I am lost, a willing victim, in the fiery heart of the furnace of Love. (Story of a Soul)
