If it were not Hagar's immediate intention, her language may at least be adopted to express a _constant sense of the divine omniscience_. No idea is so calculated to animate us in the discharge of duty, or to sustain us in submission to evil. In the ancient Olympic games, how must the consciousness of twenty or thirty thousand witnesses of their efforts have stimulated the Grecian combatants, ranged as they were around them in an amphitheatre, and consisting of the first magistrates of the kingdom! But how much more impressive and awful is the persuasion that the great eye of the universe is upon us in our Christian race; that the "King eternal, immortal, invisible," watches every movement, and beholds with approbation or kindles into wrath, as we persevere or draw back to perdition! He sees in solitude and in society, in the crowded city and the distant wilderness. On the one hand, he witnesses the aversion and rebellion of the wicked; on the other, he gathers the tears of penitence into his bottle, records the petitions of faith in his book, and amidst the music of angels, bends his listening ear to the sighs of the sorrowful. Let Christians remember that they have a mighty struggle to sustain, but their resources are inexhaustible. They have to contend with the powers of darkness and the corruptions of nature. In the issue of this contest heaven and hell are interested; the one, that you should fail; the other, that you should come off "more than conquerors." Angels are waiting on the shores of immortality to see the final result, and are already tuning their harps to sound your victory through the universe. The ascended Saviour addresses you from the skies: "Be thou faithful unto death, and I will give thee a crown of life."
