Lust is topic that is often very difficult to talk about and discuss. It's a sin that, while obvious, somehow sneaks into our lives. In this passage from the Sermon on the Mount, Jesus demonstrates for us that the fundamental problem of lust lies with how we look at other people. He invites us to be transformed by his Gospel in order that we might begin to look at others in a way that does not lead us into the temptation of lust.
