And do not fear those who kill the body but cannot kill the soul; rather fear him who can destroy both soul and body in hell. Are not two sparrows sold for a penny? And not one of them will fall to the ground without your Father's will. 

Matthew 10:28-29

"The devil frequently fills our thoughts with great schemes, so that instead of putting our hands to what work we can do to serve our Lord, we may rest satisfied with wishing to perform impossibilities."

- St. Teresa of Avila
