Very often, soldiers get killed in battle solely because they forget they are engaged in an act of war.

–A former Marine officer

Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour.

I Peter 5:8

Therefore, preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ.

I Peter 1:13
