Caleb and his 45 years of waiting

I was listening and listening and listening until finally I heard something that caught my ears.

Caleb waited 45 years for a promise to be fulfilled.
He was sent out among the 12 Israelite to search out the land of Canaan.
He came back reciting the glorious inheritance of the land as the Lord promised, whereas his fellow Israelite struck fear among the people. Moses promised the land Caleb was standing on to him.
He waited for 45 years and yet he still said he was just as before--strong and vigorous.
He followed the Lord wholeheartedly, believing. That's impressive!
