Thought is like water. Sometimes it glides over the mind as over a bed of rock; neither softening nor fertilizing; but when it is made a possible reality by the Imagination, and a vital reality by the Affections, it is now like a stream, flowing through rich farms and gardens, fertilizing wherever it comes; and again, like waterfalls, furnishing power to set ideas in motion, that shall give nutriment and warmth to the souls of millions.
The Lord, when he would condense religion into its narrowest compass, commands us to love the Heavenly Father with the whole heart and soul and mind and strength. Can this signify anything else than that Affection, Imagination, and Thought, in their whole strength, or brought down into the ultimates of life, must be consecrated to the Divine Creator of them all? So St. Paul, when he would sum up the whole Christian system in a single phrase, exclaims: "Faith, Hope, Charity. The greatest of these is Charity." Faith here expresses the religion of Thought, Hope the religion of the Imagination, and Charity the religion of the Affections, which is greatest of all because it is the vitalization of the other two.
Every act that we voluntarily perform, whether good or evil, first entered the mind as an abstract Thought; it was then shaped by the Imagination until it became a definite idea; next, it was claimed as a child by the Affections; and lastly, it was by the Affections made to come out into a use of love or an abuse of hate.
Many thoughts die in the mind without passing through all these stages. We sometimes hear a sermon that fills our Thoughts as we listen, and yet we forget it all as we turn away from the church door; for it went no deeper than our Thoughts. At another time, what we hear goes with us to our homes, haunts us through the week, and perhaps is made a standard whereby to measure the virtues or the vices of our neighbors; possibly even, we try ourselves by its rule, and our consciences are roused to pierce us with the sharp pang of remorse. All this, however, brings no change over our lives. Here Thought has passed into Imagination, has become a reality to the mind; but as yet the Affections do not warm towards it, and so it dies in the second stage of existence. Yet, again, we listen to the voice of the preacher, and his words abide in the soul until they quicken our Affections, and as we muse the fire burns. Then are our eyes lightened to perceive how all that we have heard may become realized in life; and warmed by the heavenly flame that has descended upon our altar, our souls kindle with charity, and we go forth to realize the hope that is within us in works of angelic use.
