Abram had just exercised singular generosity in absolutely refusing to enrich himself from the spoil. God reveals Himself as 'his exceeding great reward.' He gives Himself as recompense for all sacrifices. Whatever is given up at His bidding, 'the Lord is able to give thee much more than this.' Not outward things, nor even an outward heaven, is the guerdon of the soul; but a larger possession of Him who alone fills the heart, and fills the heart alone. Other riches may be counted, but this is 'exceeding great,' passing comprehension, and ever unexhausted, and having something over after all experience. Both these aspects of God's preciousness are true for earth; but we need a shield only while exposed to attack. In the land of peace, He is only our reward. 2. Mark the triumphant faith which wings to meet the divine promise. The first effect of that great assurance is to deepen Abram's consciousness of the strange contradiction to it apparently given by his childlessness. It is not distrust that answers the promise with a question, but it is eagerness to accept the assurance and ingenuous utterance of difficulties in the hope of their removal. God is too wise a father not to know the difference between the tones of confidence and unbelief, however alike they may sound; and He is too patient to be angry if we cannot take in all His promise at once. He breaks it into bits not too large for our lips, as He does here. The frequent reiterations of the same promises in Abram's life are not vain. They are a specimen of the unwearied repetition of our lessons, 'Here a little, there a little,' which our teacher gives His slow scholars. So, once more, Abram gets the promise of posterity in still more glorious form. Before, it was likened to the dust of the earth; now it is as the innumerable stars shining in the clear Eastern heaven. As he gazes up into the solemn depths, the immensity and peace of the steadfast sky seems to help him to rise above the narrow limits and changefulness of earth, and a great trust floods his soul. Abram had lived by faith ever since he left Haran; but the historian, usually so silent about the thoughts of his characters, breaks through his usual manner of narrative to insert the all-important words which mark an epoch in revelation, and are, in some aspects, the most significant in the Old Testament. Abram 'believed in the Lord; and He counted it to him for righteousness.'
