I think perhaps I was unclear or at least incomplete in my explanations of my understanding of how God supernaturally intervenes in the lives of His creation. I still stand by my position that the gifts of the Spirit that we read about in the book of Acts, such as tongues and prophecy (including direct revelation, such as God speaking to people) have ceased with the end of the Apostolic age. Now with that being said, this does not however, mean that all miracles have ceased. I am certainly not arguing, nor have I seen anyone in this thread argue, that God cannot or does not miraculously heal people in this day and age. Now if some see this as a contradiction, let me explain...
The fact that God may choose to heal someone today through a miracle is just that - a miracle wrought by the hand of God. This is completely different than the gifts of healing that the apostles possessed. Those gifts were given to the apostles to confirm their authority and the apostles regularly displayed miraculous signs. But now in this present age, our authority is based on the word of God.
As for direct revelation, I understand the idea of desiring to by sympathetic to those who sincerely believe they have heard God speak to them, and I am not saying that everyone who makes this claim I just rebuke and call them a liar in their face. But I know that there is far too much damage that can come, both to the individual and to the corporate body of Christ, if we accept the belief that the canon of Scripture remains open or incomplete. And this is exactly what those individuals who believe God still speaks via non-canonical revelation are doing.
