This is one of the most needful teachings in the church today. Much of what people pass off as prophecy is no more than fortune telling out of the heart of man or worse a spirit of divination that really can tell this false prophet some personal revelation.
Some that have a real gift, but use it to draw attention to themselves or for their own benefit.
A true prophet can be tested
By their fruit
Does their word contradict or agree with what is already written.
Does it glorify Christ Jesus?
What does the anointing that abides within you say?
Does the word produce bondage or liberty?
Does the prophecy come to pass?

Most false prophecies would stop if the word was judged by all as the scripture says.
1Co 14:29 Let the prophets speak two or three, and let the other judge.

I heard a prophet tell a very beautiful lady from Ghana that she was married to rhe wrong man. They already had one child and they were expecting at the time. The “Prophet” did not pick up on this. Some are giving out a “word” like candy. Like you said always saying what you want to hear.
In my experience when God uses someone else to give me a word, it is something He has already revealed to me, so the prophet is the second or third witness.
I have seen the real thing and believe in it and know it is a valuable ministry. But in my experience 5% of those who claim the prophetic really were genuine. This is also why we need the gifts. In this case, discerning of spirits.
Great and needful teaching. I look forward to your next submission.
Thank you!
