To blind the eye

15 And it came to pass that I looked and beheld the people of my seed gathered together in multitudes against the seed of my brethren; and they were gathered together to battle.   1 Nephi 12

To blind the eyes is not to see or acknowledge the consequences of our actions. To harden the heart is to ignore or not be willing to accept counsel. To be led into the broad roads is to give in to worldly enticements and lose the influence of the Holy Spirit in our lives.

Elder Rulon G. Craven

It is possible to practice incorrectly. 

compliance vs commitment

Joshua shows commitment in "as for me and my house, we will serve the Lord."

courage is shown in face of fear and opposition
