Joan Boney ... apostle/prophet
29Let no
corrupt communication proceed out of your mouth, but that which is good
to the use of edifying, that it may minister grace unto the hearers.
Eph. 4
Grace: a feeling of gratitude to God.
Our words should promote a feeling of gratitude to God.
But can you stop yourself from speaking. If needed we could do like Job and just put our hand over our mouth when we start to speak something. Recently I did this. To avoid speaking, I just kept putting my hand over my mouth. Several times I did this and it broke it up and I did not speak.
Job. 40:3 ... Then Job answered the LORD, and said, 4Behold, I am vile; what shall I answer thee? I will lay mine hand upon my mouth.
