When we speak or "plant" words on the spiritual side, we are planting seeds. Our spirits must react on those seeds. In Matthew 12:36 it says that we'll give account of every idle (ineffective, worthless) word that we speak.
Matthew 12:36,37 The Message Bible ... A good person produces good deeds and words season after season. An evil person is a blight on the orchard. Every one of these careless (idle, ineffective, worthless) words is going to come back to haunt you. There will be a time of Reckoning. Words are powerful ... take them seriously. (The words you speak) can be your salvation ... BUT they can also be your damnation.
So pay attention to the words you say.
Reverend Robert W. & Mary C. Butler
