I gotta have my orange juice.

Notice that Joshua exhorts us to be strong and courageous, first of all in obedience.

Only be strong and very courageous, that you may observe to do according to all the law which Moses my servant commanded you; do not turn from it to the right hand or to the left, that you may prosper wherever you go. (1:7)

Therefore be very courageous to keep and to do all that is written in the Book of the Law of Moses, lest you turn aside from it to the right hand or to the left, and lest you go among these nations, these who remain among you. You shall not make mention of the name of their gods, nor cause anyone to swear by them; you shall not serve them nor bow down to them, but you shall hold fast to Yahweh your God, as you have done to this day. (23:6-8)
