During their time in the wilderness, the Israelites encountered an array of challenges. Each challenge was meant to grow their faith in God; his love, his watch-care, and his provision for them. But instead of inspiring, educating, and challenging them, the trials they went through only served to make the Israelites, bitter, resentful and grouchy.
They complained at every opportunity and heaved long-suffering sighs at each trifle they endured. When they couldn’t find water they railed. When they were running low on food they cringed and mourned. It was easier to whine than it was to turn to God on their knees, asking for help.
But Moses was like a rock in their midst. He was unflinching in the face of trial, constantly directing the people to look up and look to God for hope. When their food ran low and they complained Moses took their petitions to God. God sent quails, a great cloud of fluttering wings rushing over the camp, ready for the taking.
And then the next day, like the dew, clammy on the ground was a small frosted seed. Manna. Sweet and light like a wafer and pliable enough to be shaped into cakes and bread. The Israelites called it Manna because they saw it as angel food, food directly from heaven and so it was. The manna fell six days a week but on the seventh day, there was no Manna. It was an object lesson, intended to teach the Israelites the importance of keeping the Sabbath holy.
A short while after the manna began to fall the children of Israel camped near Mount Sinai. It was here that God gave them his law. It was here that Moses encountered God and spoke to Him face to face. It was here that God gave Moses the schematics for the sanctuary, a living object lesson designed to teach his people the good news of salvation.
It was also at Sinai that Israel fell into deep apostasy. When Moses delayed coming down from the mountain the Hebrews turned to Aaron and demanded that he make them a god who would then lead them back to Egypt. Their fickle and reckless behavior would have hurt God deeply. After everything He had done for them; championing their freedom, defeating their enemies, providing for all their needs, at the first hint of trial they abandoned him.
