Words are powerful. They can inspire or discourage, build up or tear down, heal or hurt. The Bible repeatedly reminds us that our words carry weight—not just socially, but spiritually. Whether we’re speaking to others, praying to God, or even talking to ourselves, what we say reflects what’s in our hearts and shapes the world around us.
