Satan accuses God's people of doing wrong (Zechariah 3:1)
Then the angel showed me Jeshua the hight priest standing before the angel of the Lord.  Satan was there at the angel's right hand, accusing Jeshua of many things.

Jesus was falsely accused (Matthew 26:59-60)
Inside, the leading priests and the entire high council were trying to find witnesses who would lie about Jesus, so they could put him to death.

Christians' sins are forgiven (Colossians 1:22)
yet now he has brought you back as his friends.  He has done this through his death on the cross in his own human body.  As a result, he has brought you into the very presence of God, and you are holy and blameless as you stand before him without a single fault.

Accusations against church leaders must come from more than one person (1 Timothy5:19)
Do not listen to complaints against an elder unless there are two or three witnesses to accuse him.

Satan is known as the Accuser (Revelation 12:10)
Then I heard a loud voice shouting across the heavens,

"It has happened at last--the salvation and power and kingdom of our God, and the authority of his Christ!  For the Accuser has been thrown down to earth--the one who accused our brothers and sisters before our God day and night.
