According to my understanding the church is blessed to have a YouTube preacher like Keith Malcomson for such a time as this.
Here are 6 vital messages concerning the soon to be released horsemen of Revelation. I don't think there is a 7th to come this Sunday but I cannot rule out a postscript. He has other excellent sermons but start here.
Please, please, please take the time to at least hear the first 2 or 3 and then you will want to go on to all. Keith is very knowledgeable and aware of both history and the present.
Please pray for him as well, John.
