17. Behold, a smoking furnace. Again a new vision was added, to confirm his faith in the oracle. At first, Abram was horror-struck with the thick darkness; now, in the midst of a smoking furnace, he sees a burning lamp. Many suppose that a sacrifice was consumed with this fire; but I rather interpret it as a symbol of future deliverance, which would well agree with the fact itself. For there are two things contrary to each other in appearance; the obscurity of smoke, and the shining of a lamp. Hence Abram knew that light would, at length, emerge out of darkness. An analogy is always to be sought for between signs, and the things signified, that there may be a mutual correspondence between them. Then, since the symbol, in itself, is but a lifeless carcass, reference ought always to be made to the word which is annexed to it. But here, by the word, liberty was promised to Abram’s seed, in the midst of servitude. Now the condition of the Church could not be painted more to the life, than when God causes a burning torch to proceed out of the smoke, in order that the darkness of afflictions may not overwhelm us, but that we may cherish a good hope of life even in death; because the Lord will, at length, shine upon us, if only we offer up ourselves in sacrifice to Him.
