I watched many videos of David Owuor, and I do think he is the real thing- a true prophet.
And I ask if a prophet can be wrong?
 David said in one of his meetings that everyone who misses the Rapture goes to hell.  This does not sit right with me.  Who in the world would populate the Kingdom then?
 
  He also said the White horse rider deceives the Church, but Jesus said,"If it were possible",  and I think Christ said this in relation to signs and wonders, rather than wrong teaching that Dr. Owuor was warning about.
 
I think, when a prophetic person injects their own thinking into communication, rather than exactly what the Lord tells / shows them, we need to be cautious.
 
It is interesting though, that of all the prophetic people I have seen words from, David Owuor is the only one to speak about the Rapture.
