Pardon my ignorance here, but, from your description, how do you know that someone is "prophesying" instead of just expounding on their understanding of scripture?
What differentiates it? The fact that they are inspired? If so, how would you know they were inspired?
It is often in the quality of the wisdom and consistency of the messages imparted.
I have attended the same Pentecostal fellowship for twenty years and listened to hundreds of gifts
of interpretation and of prophesying at our meetings.
Only twice have I thought that what somebody was saying came more from them then of God.
Others agreed and there were murmurings at the meeting as people expressed their disapproval.
God sets a very high bar. His wisdom is wonderful, consoling and yet often challenging.
There are many references to scriptures and God expounds on these.
For example, Jesus might quote Matthew 7:13-14 and then go on to remind us as a church
to stay on track and not to look to the right or the left. That our walk is individual and to be
measured against the Word not others in the church.
Or, especially the Father, may cite scriptures on the day of the Lord and the end times;
here we are often admonished for our comfort zone slackness and exhorted to get out and
about preaching the word as there are still many people seeking the truth and needing to
be saved.
God tells us that the time is soon, very much sooner than many are ready for. We don't
get specifics like the supposed 23rd September that past by; but rather it will happen and
what are we doing to serve our Lord or to serve the gospel?
Jesus has a wisdom in that he can speak to an entire congregation about a particular subject
and yet as one person with specific questions of concern one can discern that in that voice
gift Jesus is also talking specifically to you - a personal answer.
Awesome.
