"Lord, I will not follow Thee," says a devout person, "by the way of consolations and self-pleasures, but only by LOVE. I desire Thee only, and nothing out of Thee for myself. If I ever mention any thing as appertaining to me, if I name myself, I mean Thee only; for Thou only art me and mine. My whole essence is in Thee. I desire nothing, which comes from Thee, but Thee thyself. I had rather suffer forever the cruel torments of Hell, than enjoy eternal happiness without Thee. If I knew I should be annihilated, yet would I serve Thee with the same zeal; for it is not for my sake, but thine, that I serve Thee. Oh, how great is my joy, that Thou art sovereignly good and perfect." [Cardinal Bona, as quoted in Fenelon's Pastoral Letter on the Love of God. See also, for similar sentiments, Bona's Principes de la Vie Chretienne, Ch. 47.]
In connection with what has been said, it will not be surprising when we say further, that the person, to whom these statements will apply, makes but little account of raptures, visions, ecstasies, special illuminations, sudden and remarkable impressions, or any thing of the kind, except so far as they tend, which, alas, is frequently not the case, to extinguish self, and to lead the soul into the abyss of the Supreme Divinity.
