Do not fear nor be afraid of them” means to be bold as we confront the issues of life. One of the tools the enemies use to attack believers is fear. You naturally become prey to anything you fear. Fear is a torment. It does not do any good to its victims. You cannot conquer the enemy that you fear.This is the main reason God mentioned to Joshua and the people of Israel to cast out every fear in them. Believers are meant to be bold as a lion, this is simply to be fearless and confident in your pursuit not minding the obstacles. Anything that cannot stop God cannot stop those that trust in Him.
