On two levels.
If you're saying Satan counterfeits that with "fortune telling", so what else is new? Satan always counterfeits what God does. But that does not invalidate God's desire to show His people by the Holy Spirit things that are to come.
Jesus discussed many of the ministries and purposes of the Holy Spirit in our lives John 14, 15, and 16. The context of Him showing us things to come is John 16:12-14:
I have yet many things to say unto you, but you cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will show you things to come. He shall glorify me: for he shall receive of mine, and shall show it unto you.
You don't want to be siding with the Pharisees of old who said the things Jesus did was by the prince of devils instead of the power of the Holy Spirit. Jesus gave stern warning regarding this (Mark 3:22, 28-30).
So--you put your faith into men, rather than Scripture?
