IHOP is a tough one. I am in a church that thinks highly of them and participates in one type of fast with them. I do not fast. I don't believe in it for the most part. But they are not really a cult - just over-zealous.
Continue your study of the scriptures. Use a Greek interlinear if you can, for you will learn a lot. I've found that much of the foundation of what such churches teach is a bit off. Not the foundation of believe in Jesus, but the other doctrines. Make good use of commentaries, but compare them, since they are very doctrinal.
And bless you. May you be filled with His Spirit and have joy unspeakable and full of glory!
