"Joshua is remembered as the one who, on the death of Moses, took command and completed the task of giving leadership to the tribes of Israel. Perhaps to comfort Joshua — who now had the responsibility for the children of Israel, who didn’t yet have a homeland — and perhaps to comfort that large body of people who had just lost their leader of more than 40 years, the Lord spoke to Joshua and said:
"'As I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee.
"'Be strong and of a good courage: for unto this people shalt thou divide for an inheritance the land, which I sware unto their fathers to give them' (Joshua 1:5–6)."

Often we take too narrow a view of life like the little twig on the end of furthest limb of a tree. It is vital with buds and blossoms full and fragrant. However, it would be foolish for that little twig to say it had no need of the limb. Cut from the tree it could not survive a single day but it would wither and die. Its beauty and fragrance gone. To be fragrant foliage we must remain attached to the source of our strength. We must study the words of the prophets in the scriptures.
