The people of Israel ate the manna 40 years until they came to a habitable land. They ate the manna until they came to border of the land of Canaan.
The Lord provided manna for the Israelite's’ 40-year wilderness trek. This was an amazing display of the Lord’s provisional omnipotence. Remember however, the Lord wanted the Israelites to enter the Promised Land straightaway.
Manna provision followed Israelite rebellion. The manna stopped once the new Israelite generation ate the Promised Land’s fruit.
We are grateful for God’s provision always, especially in times of transition. But there is a big difference between transitional provision and the blessings of the Promised Land.
