One of the telling marks of Job's friends is, they just couldn't seem to hold it back.
Not understanding the actual situation, they went on and on, spraying a mist of verbiage. It sounded good, but was a ministry of death.
There are times when all the right things to say are all the wrong things. The Holy Spirit is both bold and tender, but He will always go beyond the surface facts or circumstances.
Some are flattered when asked for advice. Others fancy themselves to hold a spiritual authority that they don't hold. Then, there are others who have strong feelings about matters that are none of their business, and they just have to be heard.
For many years, I have been surprised at how easily Christians lie, gossip and hold grudges. But more overwhelming is the inability to contain the leak of advice that is so often the fruit of spiritual immaturity.
Soldier of The Cross, be always prepared in prayer. All ground is softened by prayer. Prayer brings light for the next step, even for another. Or, prayer can still the tongue.
It is not about education, correct information or need to speak. It's about His words in His way in His time.
Make yourself available by prayer.
Aloud.
