And they asked him, saying, Master, but when shall these things be? and what sign will there be when these things shall come to pass?…
Samuel Rutherford says: "We too often believe the promises as the man that read Plato's writings concerning the immortality of the soul. So long as the book was in his hand, he believed what was said; but as soon as he laid it down, he began to imagine that his soul was only an airy vapour that perisheth with the expiring of the breath. It would greatly help to preserve us from this, and strengthen our faith, if we oftener compared Scripture with Scripture, and prediction with fulfilment." Two rabbis, we are told, approaching Jerusalem, observed a fox running up the hill of Zion. Aged Rabbi Joshua wept, but Rabbi Eliezer laughed. "Wherefore dost thou weep?" demanded Eliezer. "I weep because I see what was written in the Lamentations fulfilled: 'Because of the mountain of Zion which is desolate, the foxes fall upon it.'" "And therefore do I laugh," said Rabbi Eliezer; "for when I see with my own eyes that God has fulfilled His threatenings to the letter, I have thereby a pledge that not one of His promises shall fail, for He is ever more ready to show mercy than judgment."
