2. The ground of the call in the Revelation of God as Shield. (_a_) As to outward evils, His protection assures us, not of absolute exemption, but of His entire control of them, so that men and circumstances are His instruments, and His will only is powerful. Chedorlaomer and all the allied kings are nothing; 'a noise,' as the prophet said of a later conqueror. All the bitterness and terror is taken out of evil. If any fiery dart pass through the shield, all its poison is wiped off in passage. So there remains no reason for fear, since all things work together for good. Behind that shield we are safe as diver in his bell, though seas rave and sea-monsters swim around. (_b_) As to inward evils, our Shield assures us of absolute exemption. 'Shield of faith.' Faith is shield because it takes hold of God's strength. 3. The ground of the call in the Revelation of God as Reward. Abraham had refused all share in booty, a large sacrifice, and here he is promised, A Reward in God, _i.e._ He gives Himself in recompense for all sacrifices in path of duty. 'The Lord is able to give thee much more than these.' This promise opens out to general truth that God Himself is the true reward of a devout life. There are many recompenses for all sacrifices for God, some of them outward and material, some of them inward and spiritual, but the reward which surpasses all others is that by such sacrifices we attain to greater capacity for God, and therefore possess more of Him. This is the only Reward worth thinking of--God only satisfies the soul. With Him we are rich; without Him poor; 'exceeding great'--'riches in glory,' transcending all measure. The revelations of God as Shield and Reward are both given in reference to the present life, but the former applies only to earth, where 'without are fighters, within are fears'; while 'the latter is mainly true for heaven, where those who have fought, having God for their Shield, will possess Him for their Reward, in a measure and manner which will make all earthly experiences seem poor. Here the 'heirs of God' get subsistence money, which is a small instalment of their inheritance; there they enter into possession of it all. II
