Under Gods Command
Joshua 5:11-12 The day after the Passover, that very day, they ate some of the produce of the land: unleavened bread and roasted grain. The manna stopped the day after they ate this food from the land; there was no longer any manna for the Israelites, but that year they ate of the produce of Canaan.
God supplied manna to the hungry Israelites during their 40 years in the desert (Exodus 16:14-31). In the plentiful Promised Land they no longer needed this daily food supply because the land was ready for planting and harvesting. God has miraculously provided food for the Israelites while they were in the desert; here he provided food from the land itself. Prayer is not an alternative to preparation, and faith is not a substitute for hard work. God can and does provide miraculously for his people as needed, but he also expects them to use their God given talents and resources to provide for themselves. If your prayers have gone unanswered, perhaps what you need is within your reach. Pray instead for the wisdom to see it and the energy and motivation to do it.
