Numbers 14:20-24 (NIV)
The Lord replied, "I have forgiven them, as you asked. Nevertheless, as surely as I live and as surely as the glory of the Lord fills the whole earth, not one of the men who saw my glory and the miraculous signs I performed in Egypt and in the desert but who disobeyed me and tested me ten times--not one of them will ever see the land I promised on oath to their forefathers. No one who has treated me with contempt will ever see it. But because my servant Caleb has a different spirit and follows me wholeheartedly, I will bring him into the land he went to, and his descendants will inherit it.
Of the twelve spies who went to spy out the land God had promised, ten were doubtful that the Israelites could ever take it, but Joshua and Caleb were confident, only because they knew the promise and the power of their God. It is reasonable to trust in the Almighty One and He is trustworthy because of his promises.
I want to be like Caleb, with a different spirit, who follows God wholeheartedly.
