Concept:Joshua's success in the promised land is directly linked to the divine command given to him at the start of his leadership.
Explanation:When Joshua took over from Moses, God encouraged him with a clear charge.
In Joshua 1:6-7, God said to him: "Be strong and of good courage; for you shall cause this people to inherit the land which I swore to their fathers to give them."
God also told him to be careful to obey all the law that Moses had commanded, so that he might prosper wherever he went.
Therefore, Joshua's success did not come from being careless about God's laws, nor from personal abilities alone.
It came from his inner strength, bravery, and trust in God's promise, which made him a bold and effective leader.
This strength and courage were the distinguishing qualities that enabled him to lead Israel into the promised land successfully.
