Just as prayers, spoken or unspoken over the people we judge, are effective. Curses form in our hearts, not in our mouths.
Matthew 15:18–19 ESV … For from the heart come evil thoughts, murder, adultery, all sexual immorality, theft, lying, and slander.
Ecclesiastes 10:20 AKJV Curse not the king, no not in your thought; and curse not the rich in your bedchamber: for a bird of the air shall carry the voice, and that which has wings shall tell the matter.
