15 As the Lord had commanded his servant Moses, so Moses commanded Joshua. And Joshua did as he was told, carefully obeying all the commands that the Lord had given to Moses. (New Living Translation)
A new person starting a new job usually usually brings a new style and personality to that job. But, the church or any other organazation cannot work effectively if every change of personnel means starting from scratch. True servants will step in and continue or complete good work that others have started.
Joshua carefully obeyed all the instructions given by God. This theme of obedience is repeated frequently in the book of Joshua, partly becuase obedience is one aspect of life the individual beleiver can control.
We can’t always control understanding because we may not have all the facts. We can’t always control what other paople do or how thay treat us. However, we can control our response to life’s situations when we choose to obey God.
Whatever new challenges we may face, the Bible contains relevent instructions which we can choose to follow.
