Suffering and the discipline of the wilderness had educated the Israelites for the day of action. By what a long and tedious journey they reached their success! Behind them, yet with them still, was Sinai, whose lightnings and awful voices made them aware of the power of Jehovah into covenant with whom they entered, whose law they received. As a people bound solemnly to the unseen Almighty God they left that mountain and journeyed towards Kadesh. But the covenant had neither been thoroughly accepted nor thoroughly understood. They began their march from the mountain of the Lord as the people of Jehovah, yet expecting that He was to do all for them, require little at their hands. The other side of privilege, the duty they owed to God, had to be impressed by many a painful chastisement, by the sorrows and disasters of the way. Wonderfully, all things considered, had they sped, though their murmurings were the sign of an ignorant rebellious temper which was incompatible with any moral progress. By the long delay in the wilderness of Kadesh that disposition had to be cured. In a region not fertile like Canaan itself, yet capable of supporting the tribes, they had to forget Egypt, realise that forward not backward was their only way, that while desert after desert intervened now between them and Goshen, they were within a day's march of the Promised Land. But even this was not enough. Perhaps they might have crept gradually northward; shifting their headquarters a few miles at a time till they had taken possession of the Negeb and made a settlement of some kind in Canaan. But if they had done so, as a nation of shepherds, advancing timorously, not boldly, they would have had no strength at the opening of their career. And it was decreed that by another door, in another spirit, they should enter. Edom refused them access to the east country. They had again to gird up their loins for a long journey. And that last terrible march was the discipline they required. Resolutely kept to it by their leader, on through the Arabah, across the desert, to the "Heaps of the Outlands towards the sunrising" they went, with new need for courage, a new call to endure hardness every day. Did they faint once, and turn murmurers again? The serpents stung them in judgment, and the cure was provided in grace. They learned once more that it was One they could not elude with whom they had to do, One who could be severe and also kind, who could strike and also save. Decimated, but knit together as they had never been, the tribes reached the Arnon. And then, the first trial of their arms made, they knew themselves a conquering people, a people with power, a people with a destiny.
