Dismiss and evil thought…

As soon as we become aware of a thought that has an evil look about it, we must dismiss it immediately. We must, as it were, slam the door in its face, denying it admittance into the mind, without stopping to decipher its meaning or intention. We must shake off such wicked suggestions as quickly as we would shake off fiery sparks that landed on our clothes.
–Saint Alphonsus Liguori (1696-1787)

Do not lose heart…

Do not lose heart, even if you should discover that you lack qualities necessary for the work to which you are called. He who called you will not desert you, but the moment you are in need he will stretch out his saving hand.
–Saint Angela Merici (1474-1540)

The devil causes…

If certain thoughts bother you, it is devil who causes you to worry, and not God, Who, being the spirit of peace, grants you tranquility.
— Saint Pio (1887-1968)
