Spiritual gifting are a murky area, I find that the times when I move the best in spiritual gifting are during witnessing to others about Jesus. Often I will just be using the natural mind and God will give me insight. But often when I TRY to use a gift I fail. I often when I am at home try to prophecy, i.e. hear from God, and I fail. But I am often on the street witnessing and my conversation uncovers secrets about the person. As an example I was witnessing last weekend, and just as I spoke not even trying to prophecy, God told me one guy like soccer, and he did, he showed me how a family was related, now I did not even try to prophecy, it was just as an example, as I spoke the the guy about Jesus, he was out side a game shop I just said do you like computer games, he said no, and as I spoke I felt internally to say do you like soccer, he said yes. For me it is not so much direct prophecy, but God dropping hints.
For you I feel as the other have said you need to get deep into the bible. The bible also says when you pray believe and you will have the thing you ask for. We all have a level of faith, what we are comfortable asking for. As you get to know God more and more and get deeper into the Spirit you will find you will be able to ask for bigger and bigger things and see them come to pass. But the faith to see these things must be based upon the bible. Firstly in your situation the thing you are seeing are robbing your peace, they need to be told to rack off, they are basically demons. Don't fear, most of us have seen a demon or two, but they are there to confuse you. God wants to put an inner strength into you, as the bible says the fruit f the spirit is love, joy, and peace. Your life should, and will become in God, a shining tower of love, joy, and peace, from that tower you will be able to see out clearly into the world, and see the darkness, and bring the same peace you have into it. But boy is it hard!!! It is not easy. I know God may tell me to do 100 things and I might t do 2 of them. Getting to know God is an adventure. But our goal as you have said should be to help others. I pray that God help you grow in the gift to help others.
