There is a saying that God gives us what we need and not always what we want. People always cheer until they later find out that it includes them. We want our cake and eat it too. We want God and sin.
Many of the Israelites wanted God to provide them with food, water, and the promised land but did not want to follow His instructions for it. “Thanks God for this food that all we have to do is pick up off the ground but we’ll take it from here.” Yet the food spoiled over night if they tried to keep it. they took the manna without question but then did not trust God for the next day’s food or maybe they were lazy and didn't want to wake up early, who knows.
