Second Nephi 7:8

And the Lord is near, and he justifieth me. Who will contend with me? Let us stand together. Who is mine adversary? Let him come near me, and I will smite him with the strength of my mouth.

In the strength of the Lord in His calling as the Messiah, Christ will stand with us. He will be our advocate and our protector. His weapons are not armies but the words He speaks. He who spoke and the world was and the heavens came into being, will speak His words on our behalf, and our enemies of sin and sorrow will be vanquished.
