Joshua 1:5 “No one will be able to stand against you all the days of your life. As I was with Moses, so I will be with you; I will never leave you nor forsake you.”
Brethern, when God promised that He would lead, comfort, and protect us ALL the days of our lives His promise was not exclusive. No, Moses isn’t the only one that God can succeed, Joshua. If He told you that Canaan is now conquerable, then ye shall possess for He will not fail nor forsake thee!
