Thanks to Jesus,
Satan can not use our sins against us.
"He forgave us all our sins,
having canceled the written code, with its regulations,
that was against us and that stood opposed to us;
he took it away, nailing it to the cross.
And having disarmed the powers and authorities,
he made a public spectacle of them,
triumphing over them by the cross."
Colossians 2:13b-15 NIV
