You can't have it both ways. If you believe there are modern prophets out there (other than Joseph Smith, Ellen G. White, William Branham*, etc. whom most Christians will not accept since they also introduced false teachings) it is up to you to present their prophecies. Otherwise you should accept what Paul said in 1 Cor 13:8. Christians should not be afraid to be called Cessationists, since Paul said that three spiritual gifts would cease, and cease they did.
Several people have also critiqued Kim Clement and called him a false prophet. I don't know enough about him, but in general I do not believe there are genuine prophets today.
Prophecy is divine revelation, and according to the apostle-prophet John, prophecies would cease after he finished writing the Revelation: For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: (Rev 22:18)
What was John saying? Any additional prophecies after 95 AD would be unacceptable to God. And as a matter of fact, none of the Early Church Fathers ever claimed to be either an apostle or a prophet.
*Note, William Branham either invented the Serpent Seed doctrine, or promoted this false doctrine, which claims that the Devil had sexual intercourse with Eve and produced Cain. Here is what he said, while contradicting the Bible: Before Adam ever had carnal knowledge of Eve, the serpent had that knowledge ahead of him. And that one born of it was Cain. Cain was of (born of, begotten of) that “Wicked One,” (I John 3:12)
However, this is what we read in Scripture: And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the LORD. (Gen 4:1) [Note" "knew" is a biblical euphemism for sexual intercourse]
So the Bible tells us that the first child of Adam and Eve was Cain, and that Eve recognized that she had received this son from the LORD. Indeed the name "Cain" (Hebrew Qayin) means "possession" or that which is acquired, hence "I have gotten". So what 1 John 3:12 means is that Cain had the character and attributes of Satan, who was also a murderer from the beginning.
