Joshua 23

"'So be very careful to follow everything Moses wrote in the Book of Instruction. Do not deviate from it, turning either to the right or to the left. Make sure you do not associate with the other people still remaining in the land. Do not even mention the names of their gods, much less swear by them or serve them or worship them. Rather, cling tightly to the Lord your God as you have done until now.'" v.6-8
Joshua knew the nation's weak spots. Before dying; he called the people together and gave commands to help hem where they were most likely to slip:
1.) Follow all that is written in the Book of Instruction without turning aside.
2.) Don't associate with the pagan nations or worship their gods.
3.) Don't intermarry with the pagan nations.
These temptations were right in their backyard. Our associations and relationships can be temptations to us as well. It's wise to identify our weak spots before we break down. Then we can develop strategies to overcome these temptations instead of being overcome by them.
