Very powerful stuff. If we all could do that all the time when faced w/ Satan and/or daily temptations. Jesus stuck 2 his guns and trusted & believed in God's words & repeated scripture/God's words back 2 the devil and he went away. If we could do that all the time every time the devil wouldn't win at all...ever.

Matthew 4:1-9, Matthew 4:10 and Matthew 4:11
