 Verse 5, God said, No one will be able to stand up against you all the days of your life. As I was with Moses, I will be with you. I will never leave you or forsake you, so be strong and courageous. You will lead these people. Joshua's work was to get the people out of the wilderness into the promised land. And he says you have his power. No one will be able to stand up against you all the days of your life because you'll have the power of God in your life to enable you to do the work.
