I don't need Derek whomever. I believe the Word of God which is clear. Gifts have ended and are no longer necessary. Apostles are dead and Gifts cannot be enabled as a result thereof. That's very clear by scripture irrespective of what anyone says including Derek or you. Believe what you like.
You need to become teachable. There is absolutely nothing in God's word that states that the gifts have ceased. They will eventually. If what we see now is perfection, then I'm Paddington Bear.
Reality says that gifts have not ended. Abused, confused, misunderstood, yes. And obviously, in some cases, ignored. However, the real does exist and is necessary. A timely word of knowledge can save someone from a world of of hurt. A prophecy can encourage a struggling believer. We had a young couple in our small fellowship. My wife told me that they would be leaving. I was most surprised. They seemed very much committed. A couple of years later, they were gone.
Perhaps you are so mighty in God that you need no one to help you, lead you or guide you. Good for you. Lesser mortals like myself have yet to arrive at perfection in holiness.
