Okay, I watched the whole video, thanks for posting it here.
Sometimes clicking on links can bring a virus to your computer, easier than clicking onto something on this site, but still not impossible.
I would like to point out that you could have put this video topic in your own words by simply saying you believe that we are all related to someone Jewish and that makes us all Jews; or, you could have said something truer and more profound and that would be that IT DOES NOT MATTER who is related to Abraham anymore because God says not of by human descent/blood relations to Abraham.
We are all related to Eve, for Eve is everyone's mother. How do I know? I know because the Bible says so plainly: Genesis 3:20 Adam named his wife Eve, because she would become the mother of all the living.
So what makes us of a particular ethnicity? Well, it is said that it takes up to the 6th generation to remove any resemblance of an ethnicity from your DNA. For instance, if a white person marries a black person, and their half black and half white children married and had children from white spouses, their children would only then be part black; and then, if those part black and 3/4th white descendants had children with all white people, then the part black would now be 1/8th black, going further in the same ethnicity would be 1/16 black, and then virtually non detectable of the black race in those descendants. So it seems that that part is a little lost in that pastor's proof.
However,what does matter is that we are all related to Eve, and that God does NOT CARE anymore who has more of Abraham's blood, and as Paul says, "...instruct certain men not to teach false doctrines or to devote themselves to myths and endless genealogies. Such things promote controversial speculations rather than advancing God's work--which is by faith."
It only matters that we are related to Abraham by having the same faith as Abraham had. All these people who think that Jews are special people with a special end time that no one else has is well, wrong. God cut off unbelieving Jews and bound them with the disobedient Gentiles. We are all the same when it comes to blood. It only matters to whom one is blood related to Jesus and the shedding of Jesus' blood on the cross.
