In God we have the strength and the ability to face any challenge that comes our way.

And they returned from exploring the land at the end of forty days. 26 And they went and came to Moses and Aaron, and to all the congregation of the children of Israel, in the desert of Paran, in Kadesh, and they reported to them and to all the congregation, and shewed them the fruit of the land. 27 And they told them, saying, We came to the land to which you sent us, which indeed flows with milk and honey; and this is the fruit of it. 28 But the people who inhabit that land are strong, and the cities very large and fortified; and we also saw the children of Anak there. 29 Amalek inhabits the Negev, and the Hittite, the Jebusite, and the Amorite inhabit the mountains, and the Canaanite inhabits by the sea, and by the bank of the Jordan.
30 Then Caleb silenced the people before Moses and said, “Let us go up at once and take possession of it, for we are more powerful than they.” 31 But the men who went up with him said, “We cannot go up against the people, for they are too strong for us.” 32 Then they spoke evil of the land they had explored to the Israelites, saying, “The land we have gone through to search it is a land that swallows up its inhabitants; and all the people we saw in it are men of great stature. 33 We also saw giants there, Anak, a race of giants; and we were like grasshoppers to ourselves, and so we appeared to them.”
Israelites Rebel Against the LORD
14 Then the whole congregation cried out and cried out, and the people wept that night. 2 Then all the Israelites grumbled against Moses and Aaron. And all the people said to them, “Would that we had died in the land of Egypt! Would that we had died in this wilderness!” 3 Why has the LORD brought us into this land to fall by the sword, and to have our wives and our children taken as plunder? Would it not be better for us to return to Egypt? 4 They said to one another, “Let us appoint a captain and return to Egypt.” 5 Then Moses and Aaron fell face downwards before all the congregation of the children of Israel. 6 Then Joshua the son of Nun and Caleb the son of Jephunneh, who were among those who had searched the land, tore their clothes. 7 They said to all the congregation of the children of Israel, “The land through which we have gone to search it is an exceedingly good land. 8 If the LORD is pleased with us, He will bring us into this land and give it to us, a land flowing with milk and honey. 9 Therefore do not rebel against the LORD, nor fear the people of this land, for we will eat them as bread; their protection has departed from them, and the LORD is with us; do not fear them.” 10 Then all the multitude spoke of stoning them.
But the glory of the LORD appeared in the tabernacle of meeting to all the children of Israel,

Numbers 13:25-14:10

God was very clear about what He told the Israelites, later they took and possessed the land of Canaan, they needed a land to settle and prosper and be a strong nation, God chose the best place for them.

With God's guidance Moses sent 12 men to inspect the area, these spies approached and when they returned with the reports, 10 of those spies told terrible and unfavorable stories, totally alarming, these 10 men saw obstacles and difficulties in front of them. But of those 12 men only two, "Caleb and Joshua" saw a totally different picture, he had no doubt that he could conquer this land.

30 Then Caleb silenced the people before Moses and said, "Let us go up and take possession of it, for we are more powerful than they."

Numbers 13:30

Caleb and Joshua saw these possibilities because they were simply focused on the promises of God and not on those difficulties that seemed to be greater, the confidence of both was in the words given by God to Father Abraham: "To your descendants I will give this land."

For the rest of the men of little faith, the stories of what they had seen were totally devastating, a land full of giants and fortified cities that were scary, although these would be an obstacle that anyone could fear, God had shown and promised that with confidence in Him they could overcome any of the obstacles that arise, we remember that God had opened the Red Sea so that His people could walk dry through it to free us from the oppression of the Egyptians, and after that He fed them for 40 years in the desert.

When we focus on obstacles we are simply allowing our vision to be distorted, but if it is God who has called us to put something into practice, the only thing we have to do is see that He will give us the solution and help us overcome any obstacle that appears on our path.
