Jesus said to His disciples - "I don't have much more time to talk to you, because the god (Satan) of this world approaches. He has no power over me, John 14:30

When  Satan comes to you what will he find?   Will he have evidence of unconfessed sin - giving him  the  right to accuse you before God and Angels?    If we abide in Christ  and walk in the light as He is in the light - then like Jesus - Satan has no power over us.

He who walks blamelessly will be delivered, But he who is crooked will fall all at once. Proverbs 28:18
