When a person opens his mouth and speaks, his spirit also speaks.

.. His spirit will find some measure of release in the opening of his mouth however much he may try to contain himself. Our ability to discern what his spirit is saying depends on the measure of our exercise in the Lord. If we are exercised, we will be able to discern the words he has uttered, the words he has refrained from uttering, and even the words in his spirit. ~
