Be bold. Don’t hesitate.
In a sermon on John 1:14, Martin Luther tells us how to beat back the devil when under his attack.
Little is gained against the devil with a lengthy disputation, but a brief word and reply such as this is effective: “I am a Christian, of the same flesh and blood as my Lord Christ, the Son of God. You settle with him, devil!” Such a retort would soon make him depart.
When under attack, let Christ be your strength. People who dialogue with the devil don’t usually win. Jesus being the exception, send the devil to him.
