Then Caleb quieted the people before Moses, and said, “Let us go up at once and take possession, for we are well able to overcome it.” Numbers 13:30

Moses sent twelve men to spy out the land of Canaan and they returned forty days later. Each man saw a good land with an abundance of fertile land and streams. They returned with pomegranates, figs, and a bunch of grapes that took two men to carry.
However, most of the men reported the impossibility of taking the land by force saying, “We saw the giants (the descendants of Anak came from the giants); and we were like grasshoppers in our own sight, and so we were in their sight.” Numbers 13:33

Only Caleb and Joshua believed they should proceed forward and take the land.

This was a pivotal point in the history of Israel. This act of faithlessness, doubt, and rebellion caused them to wander through a harsh wilderness for the next forty years as punishment. They struggled to scrape out an existence while constantly moving around and fending off attacks from neighboring nations.

The only thing four decades of wandering changed were the people involved in going into the land. Everyone that refused to go died in those wilderness years leaving a new generation to enter the same land and fight the same people as they would forty years earlier.
Time did not remove the problem of giants in the land. It did not remove the fortified cities.
Yet, I believe forty years of wandering toughened a new generation to become more dependent on God and stronger in their faith.

We are not so much different. We hear God say to move forward but we see a giant problem in the way and determine we cannot go on.
This is where you must determine, “do I want to play it safe or do I want an abundant blessing from God?”
