Since Esther was in San Francisco, we listened to the first part (from time 3.04 to 23.19) of a video by Louie Giglio called "Winning the Battle of the Mind", which can be found at https://youtu.be/p_hJw7w2Yso.
Starting with the devil's temptation of Eve in Genesis 3, he asks what thoughts have you allowed to raise doubt in your mind. Then he reminds us that Jesus has already won the battle and has established a beachhead called Victory to enable us to tear down the strongholds that the devil has tried to establish in our minds.
