This article contains a fair amount of Hebrew, so to insure that this article is presented in a correctly formatted form, it is only available at this time as a MS Word document. You may download it here.
You may need Hebrew fonts to read the Hebrew portions of this document. You can get them here. I don't remember for sure where I got them, as I have had them for a LONG time. What I do remember, though, is that they were offered for free. As I freely received, so freely do I give. :)
The video below about Yeshua is sure to be a blessing to all believers.
