God promised Moses that He would deliver the children of Israel from the hand of the Eyptians and bring them unto a "land flowing with milk and honey."
When children of Israel came to that land, twelve representatives of Israel were sent to spy in the promised land. They found a land which was "exceeding good land." And indeed it was a land in which "floweth with milk and honey."
Two of the twelve were ready to possess the land, Caleb and Joshua, even though the inhabitants of the land appeared stronger than the Israelites. Ten of the men only saw "the giants" as they described them.
The ten were able to cause the hearts of the children of Israel to despair and to murmur against the Lord for bringing them to that place. According to the Scriptures, they cried and wept that night.
Then Caleb spoke to the people:
"The Lord is with us: fear them not." This is all we need to say. Even more for us, than for Caleb, the Lord is in us. What have we to fear? There is nothing we can gaze upon, no giants in our land, that is greater than our Lord. Our Lord loves to protect, to provide for and to commune with His children.
We would do anything to protect our children. Even after they become adults, we still have that desire, that urge to protect them and keep them from harm. Why do we doubt our Lord's desire to protect His children? Especially when we consider the price to purchase His "dear children" (Ephesians 5:1) was His Son's life.
"For it became Him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the Captain of their salvation perfect through sufferings." Hebrews 2:10
So any time, every time, we are tempted to fear let choose instead to look to the "Captain" of our salvation and say with Caleb, "The Lord is with us: fear them not."
