The devil is the father of lies. The spiritual fight, in essence, is a fight with him, with his angels and his servants. Actually – our eternal life is at stake; we will be either eternally saved or eternally condemned, and this is no triviality! The spirit of lie manifests itself in different forms and works in different variants. We must be aware that this infection of lie and sympathy for it is a sad heritage of original sin in each one of us. So it is not enough to fight just with an outer enemy, but we have to fight even with this infection in us, with our old nature, the old self. Therefore Jesus’ word still holds true: “Deny yourself.”
