Satan is legalistic.
He takes precedence with what you say.
Proverbs 6:2. Thou art snared with the words of thy mouth, thou art taken with the words of thy mouth
Matthew 12:35-37. 35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things. 36 But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. 37 For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
Not just what you say about being a child of God, every word that you say.
The good news is that you can repent, and God can intervene.😇 1 John 1:9
