You are never too young or old for God to work in your life.
“So Hebron has belonged to Caleb son of Jephunneh the Kenizzite ever since, because he followed the Lord , the God of Israel, wholeheartedly.”
What is the Caleb principle? You are never too young or old for God to work in your life. The name Caleb means “All Heart” or “Wholehearted.” Caleb was one of the twelve spies that Moses sent to spy out land of Canaan. Ten of the spies brought back an evil report. They did not believe the land could be conquered. Caleb and Joshua brought back a good report and urged Moses and the people and Moses to proceed to conquering the land of Canaan. At this time Caleb was forty years old when God promised to give him Hebron for an inheritance. At this time, he was eighty years old when he claimed his inheritance. His testimony was that he was as strong at eighty as he was at forty. In his character, he was true to his name, and his fame is still spread abroad wherever people study God’s Word. He followed God fully,” and was rewarded abundantly.
The Hebrew for the phrase “I have wholly followed the Lord” describes a ship going out in full sail. "Will you please tell me in a few words," said a Christian woman to a minister, "what you think 'consecration' means?" Holding out a blank sheet of paper, the minister replied, "It is to sign your name at the bottom of this blank sheet and let God fill it in as He wills." (From Practical Bible Illustrations)
In this passage, Caleb chose “Hebron” as his inheritance. The word “Hebron” conveys within itself the idea of fellowship, love, and communion. This was the place that he loved and cherished. The devil does not want believers to occupy the place of Hebron.
