It was in this year 1840, also, that a further object was embraced in the work of the Scripture Knowledge Institution, namely, the circulation of Christian books and tracts. But, as the continuance and enlargement of these benevolent activities made the needs greater, so, in answer to prayer, the Hand of the great Provider bestowed larger supplies. Divine interposition will never be doubted by one who, like George Muller, gives himself to prayer, for the coincidences will prove too exact and frequent between demand and supply, times and seasons of asking and answering, to allow of doubt that God has helped. The 'ethics of language' embody many lessons. For example, the term 'poetic retribution' describes a visitation of judgment where the penalty peculiarly befits the crime. As poetic lines harmonize, rhyme and rhythm showing the work of a designing hand, so there is often harmony between an offense and its retribution, as when Adonibezek, who had afflicted a like injury upon threescore and five captive kings, had his own thumbs and great toes cut off, or as when Haman was himself hung on the gallows that he built for Mordecai. We read in Psalm ix. 16: "The Lord is known by the judgment which He executeth: The wicked is snared in the work of his own hands." The inspired thought is that the punishment of evil-doers is in such exact correspondence with the character of their evil doings as to show that it is the Lord executing vengeance--the penalty shows a designing hand. He who watches the peculiar retributive judgments of God, how He causes those who set snares and pitfalls for others to fall into them themselves, will not doubt that behind such 'poetic retribution' there is an intelligent Judge. Somewhat so the poetic harmony between prayer and its answer silences all question as to a discriminating Hearer of the suppliant soul. A single case of such answered prayer might be accounted accidental; but, ever since men began to call upon the name of the Lord, there have been such repeated, striking, and marvelous correspondences between the requests of man and the replies of God, that the inference is perfectly safe, the induction has too broad a basis and too large a body of particulars to allow mistake. The coincidences are both too many and too exact to admit the doctrine of _chance._ We are compelled, not to say justified, to conclude that the only sufficient and reasonable explanation must be found in a God who hears and answers prayer. Mr. Muller was not the only party to these transactions, nor the only person thus convinced that God was in the whole matter of the work and its support. The _donors_ as well as the receiver were conscious of divine leading.
