The Screwtape Letters Summary Strategies of Temptation

Lewis suggests using humor to eliminate shame and make sin seem acceptable. He believes humor is a powerful tool for making people feel comfortable with their sins.

They may also be tempted to keep up a budding friendship based on the idea that they are doing good by associating with people who are not good for them.

Avoiding Subtle Temptations

Lewis’s description of subtle, gradual temptation is a good reminder that we can be tempted by things that seem harmless or even good. For example, we might be tempted to overindulge in food or drink when we’re bored or when we’re celebrating a special occasion. We might also be tempted to keep up a friendship with someone who is a bad influence because we think we can help them. To avoid these...
