Many look back to the Israelites, and marvel at their unbelief and murmuring, feeling that they themselves would not have been so ungrateful; but when their faith is tested, even by little trials, they manifest no more faith or patience than did ancient Israel.
God had promised to be their God, to take them to Himself as a people, and to lead them to a large and good land; but they were ready to faint at every obstacle encountered in the way to that land. . . . They forgot their bitter service in Egypt. They forgot the goodness and power of God displayed in their behalf in their deliverance from bondage. They forgot how their children had been spared when the destroying angel slew all the first-born of Egypt. They forgot the grand exhibition of divine power at the Red Sea. They forgot that while they had crossed safely in the path that had been opened for them, the armies of their enemies, attempting to follow them, had been overwhelmed by the waters of the sea. They saw and felt only their present inconveniences and trials; and instead of saying, "God has done great things for us; whereas we were slaves, He is making of us a great nation," they talked of the hardness of the way, and wondered when their weary pilgrimage would end.
The history of the wilderness life of Israel was chronicled for the benefit of the Israel of God to the close of time. The record of God's dealing with the wanderers of the desert in all their marchings to and fro, in their exposure to hunger, thirst, and weariness, and in the striking manifestations of His power for their relief, is fraught with warning and instruction for His people in all ages. The varied experience of the Hebrews was a school of preparation for their promised home in Canaan. God would have His people in these days review with a humble heart and teachable spirit the trials through which ancient Israel passed, that they may be instructed in their preparation for the heavenly Canaan.
