I recollect when I stood on the summit of Etna, and darted my gaze down the crater; the immediate vicinity was discernible, till, lower down, obscurity gradually terminated in total darkness. Such figures exemplify many truths revealed in the Bible. We pursue them, until, from the imperfection of our faculties, we are lost in impenetrable night. All truths, however, that are essential to faith, 'honestly' interpreted; all that are important to human conduct, under every diversity of circumstance, are manifest as a blazing star. The promises also of felicity to the righteous, in the future world, though the precise nature of that felicity may not be defined, are illustrated by every image that can swell the imagination: while the misery of the 'lost', in its unutterable intensity, though the language that describes it is all necessarily figurative, is there exhibited as resulting chiefly, if not wholly, from the withdrawment of the 'light of God's countenance', and a banishment from his 'presence!'--best comprehended in this world, by reflecting on the desolations which would instantly follow the loss of the sun's vivifying and universally diffused 'warmth'. You, or rather 'all', should remember, that some truths, from their nature, surpass the scope of man's limited powers, and stand as the criteria of 'faith', determining, by their rejection, or admission, who among the sons of men can confide in the veracity of heaven. Those more ethereal truths, of which the Trinity is conspicuously the chief, without being circumstantially explained, may be faintly illustrated by material objects.--The eye of man cannot discern the satellites of Jupiter, nor become sensible of the multitudinous stars, the rays of which have never reached our planet, and, consequently, garnish not the canopy of night; yet, are they the less 'real', because their existence lies beyond man's unassisted gaze? The tube of the philosopher, and the 'celestial telescope',--the unclouded visions of heaven, will confirm the one class of truths, and irradiate the other. The 'Trinity' is a subject on which analogical reasoning may advantageously be admitted, as furnishing, at least, a glimpse of light, and with this, for the present, we must be satisfied. Infinite Wisdom deemed clearer manifestations inexpedient; and is man to dictate to his Maker? I may further remark, that where we cannot behold a desirable object distinctly, we must take the best view we can; and I think you, and every candid and inquiring mind, may derive assistance from such reflections as the following.
