Psalm 37:10-11 amp

For yet a little while, and the evildoers will be no more; though you look with care where they used to be, they will not be found.  But the meek (in the end) shall inherit the earth and delight themselves in the abundance of peace.  

The power of the meek is their faith and trust in God.  The knowledge of their covenant rights and protection that comes from God defeats all evil.  A person who has absolute assurance in God and His word will overcome this world.  Even as the world turns upside God will take care of the meek.
