You. Psalms 119:11.
The problem with sin is that it cultivates negative energy. From the
mind where it begins or originates, it creeps down into your heart.
Then you're in trouble. That's why it's not a sin to think a bad
thought, if you dismiss it. You did not act on it. Therefore, it is
not a sin. But if you dwell on the wrong thought, it will creep on
down into your heart and become a part of you. So, above all else,
safeguard your hearts.
Dutch version / Nederlandse versie: Zonde cultiveert negatieve energie
