Again, we do not see Caleb coming to Joshua with arrogance but with confidence, trusting that God is going to stand up for what He said. Believing that God also would help them and drive out the inhabitants of the land. Now, this belief was not based on his own strength but it was a total confidence in God. You know, at this point, Caleb is 85 years old. Turn to read verse 10 and 11.
I do not think he was boasting. I do not know if he had the same strength as an 85-year-old as a 40-year-old man, but I know how it is as you get older: your mind does not change. Your body changes, but your mind does not change. But he acknowledged he knew what God had promised him. But he also knew that it was not because of his strength. It was because he knew that it was his God that would preserve him.
