To quote Martin Luther on Galatians 1:3:
Let us equip ourselves against the accusations of Satan with this and similar passages of Holy Scripture. If he says, "Thou shalt be damned," you tell him: "No, for I fly to Christ who gave Himself for my sins. In accusing me of being a damnable sinner, you are cutting your own throat, Satan. You are reminding me of God's fatherly goodness toward me, that He so loved the world that He gave His only-begotten Son that whosoever believeth in Him should not perish, but have everlasting life. In calling me a sinner, Satan, you really comfort me above measure." With such heavenly cunning we are to meet the devil's craft and put from us the memory of sin.
When Satan accuses you of sin, you remind him of Christ's forgiveness. Same thing when it's Satan's agents in the world--some of whom, apparently, profess Christianity themselves.
When Satan tempts me to despair
And tells me of the guilt within,
Upward I look and see him there,
Who made an end of all my sin.
Because the sinless Savior died,
My sinful soul is counted free,
For God the just is satisfied
To look on him and pardon me.
--Charitie Lees Smith, "Before the Throne of God Above"
And since Satan's agents appear to be concern trolls, trying to derail the work of the church under the pretext of "impact on the community," we could also quote Nehemiah 6:3: "I am doing a great work and I cannot come down. Why should the work stop while I leave it and come down to you?"
