[4] It is in our own bosom that the power of temptation is found. Temptation is but a spark; and if a spark fall upon ice, if it fall upon snow, if it fall upon water, what is the harm of a spark? But if it fall upon powder--the powder is yours, the spark only is the devil's.--_Beecher._ The power of temptation is in proportion to the nature of the soul tempted. A thoughtless miner takes an uncovered light into the mine: where there is but little gas, there is but a wavering and flickering of a transient flame,--hardly flame, indeed; but where there is an accumulation of gas, the uncovered light occasions an explosion which shivers the rocks and brings swift destruction upon all who are in the mine. In both cases it was the same mine, the same miner, but the condition of the air was different. So is it with the fiery darts of the wicked one; they are shot into all human hearts, and just in proportion to the materials, so to speak, which are to be found there, will be the success or failure of the enemy.--_Dr. Parker._ ISAIAH'S VISION OF THE LAST DAYS. ii. 1-5. _The word that Isaiah the son of Amoz saw, &c._ 1. The marvellous power of the ancient prophets in giving embodiment and figure to the Word of God. It was a "word" that Isaiah saw; not that he heard, but that shaped itself before his vision, and made him glad, as if a new star had arisen to guide him. 2. Isaiah speaks with magnificent confidence as to the summing up of earthly dispensations. Casting his eye over all the uproar and tumults of intervening time, he sees a heavenly repose settling on the engagements and destinies of mankind. Herein is the peculiar power of the old prophets, viz., that they did not confine their attention within a brief and inadequate period, but projected their minds over historic spaces within which, so to speak, God had room to disclose somewhat of the proportions and significance of His plans. The whole year can never be judged from any one season. The prophets seemed to see things in their _wholeness,_ and this made them calm in the midst of transitory confusion and distress. 3. The house of the Lord is to be exalted above all rivalry. The strength of the hills is to be a pedestal for the sanctuary. At the last right shall be uppermost, and holiness supreme. In the "last days" the house of the Lord shall exert a universal fascination; nation shall challenge nation to go up in holy and triumphant procession to the heights of Zion; and the voice of other allurements shall be lost in the infinite charm of the invitation. 4. Nor is this to be the indulgence of a mere sentiment; it will be the expression of a desire to be spiritually right, and thus to be spiritually secure: "He will teach us of His ways, and we will walk in His paths." Lawless sentiment is to have no place in spiritual discipline. We are not called to a high revel, but to a
