For me. . .if there is a tongue first. . .I do not know until the words come pouring out in English what is going to be said. When I first started stepping out in this gift all I did was the tongue and I depended on there being an interpreter.
Then, when I would feel the prompting of the HS for a tongue and I did not know if there was an interpreter, I saw the need for me to also pray for the interpretation. That way the message whould not have to be squelched due to me not knowing.
Now I can do both. But mainly, instead of the tongue, I usually just give the word in English. . .unless the Spirit moves differently.
The most specific word that I personally have received was just the word in English, not the tongue first.
I had just gone through an extremely stressful situation with a job I'd had for 8 years and had been fired due to a fellow employee who did not like me, becoming my boss. It was a Christian ministry but this man had made up several accusations about me and it was a very hurtful thing. He had made some "rule" changes that technically, were not legal and in the long run would cause very big problems. I had confronted him on these things.
Several co-workers had told me I was being foolish to put my job on the line and should have just been quiet over the discrepencies. Since what I did envolved ministry expenses it was my job to address these issues, however, as my personality tends to do, I had mulled over things, over and over again, and soon found myself, thinking I could have done this differently or said that differently, etc., etc.. "Maybe it really was my fault". Basically, beating myself up.
Anyway, I went to a woman's conferance that my church was part of. It was something I had decided to do at the last minute. . . and I went there directly from work. I was able to find a seat with other woman from my church.
It was during the worship service and we were all standing and worshipping God. Then it got quiet and another woman at the pulpit began to give a word. This woman could not see me from where she was and I could not see her. We had never met and as far as I know had never even been in the same room together before.
I can't remember what was said, word for word but it was something to the effect of "You thought you were going to be working there for ever, but it was not in My plan for you to do that". I had loved my job. . .I did want to work there forever. Then, right at the end she said, "Furthermore
Barbara, (that's my name, and I was NOT wearing a name tag), while others called you foolish and told you to be quiet, I call you faithful, because you said what I told you to."

How much more specific could God get ey?
