The first step in the leisurely march of the divine deliverance is the provision for checking the Egyptian advance and securing the safe breaking up of the Israelitish camp. The pursuers had been coming whirling along at full speed, and would soon have been amongst the disorderly mass, dealing destruction. There was no possibility of getting the crossing effected unless they were held at bay. When an army has to ford a river in the face of hostile forces, the hazardous operation is possible only if a strong rearguard is left on the enemy's side, to cover the passage. This is exactly what is done here. The pillar of fire and cloud, the symbol of the divine presence, passed from the van to the rear. Its guidance was not needed, when but one path through the sea was possible. Its defense was needed when the foe was pressing eagerly on the heels of the host. His people's needs determined then, as they ever do, the form of the divine presence and help. Long after, the prophet seized the great lesson of this event, when he broke into the triumphant anticipation of a yet future deliverance,--which should repeat in fresh experience the ancient victory, The Lord will go before you; and the God of Israel will be your rearward.' In the place where the need is sorest, and in the form most required, there and that will God ever be to those who trust Him.
We can see here, too, a frequent characteristic of the miraculous element in Scripture, namely, its reaching its end not by a leap, but by a process. Once admit miracle, and it appears as if adaptation of means to ends was unnecessary. It would have been as easy to have transported the Israelites bodily and instantaneously to the other side of the sea, as to have taken these precautions and then cleft the ocean, and made them march through it. Legendary miracle would have preferred the former way. The Bible miracle usually adapts methods to aims, and is content to travel to its goal step by step.
Nor can we omit to notice the double effect of the one manifestation of the divine presence. The same pillar was light and darkness. The side which was cloud was turned to the pursuers; that which was light, to Israel. The former were paralyzed, and hindered from advancing a step, or from seeing what the latter were doing; these, on the other hand, had light thrown on their strange path, and were encouraged and helped to plunge into the mysterious road, by the ruddy gleam which disclosed it. So every revelation is either light or darkness to men, according to the use they make of it. The ark, which slew Philistines, and flung Dagon prone on his own threshold, brought blessing to the house of Obededom. The Child who was to be set for the fall,' was also for the rising of many.' The stone laid in Zion is a sure foundation,' and a stone of stumbling.' The Gospel is the savoir of life unto life, or of death unto death. The same fire melts wax and hardens clay. The same Christ is salvation and destruction. God is to each of us either our joy or our dread.
