This is my understanding of the original video of Brother Eli. Everyone is encouraged to watch and respond:
Mk. 16:9-20 is not a true part of the Bible. Those verses are known as the "Longer Ending of Mark" by Bible scholars. They do not appear in the older manuscripts of Codex Vaticanus and Codex Sinaiticus.
Even, the church historian Eusebius excluded them from his canons, explaining that the best copies of Mark he knew did not include them. Also, Jerome expressed doubt over the authenticity of these verses. Besides, the English translation of Codex Sinaiticus of Mark 16 stops at verse 8.
Brother Eli himself was at the British Library, London where he saw the oldest Codex Sinaiticus which is about 1,600 years old written in the 4th century. He saw that this Codex does not contain Mk. 16:9-20.
Those verses actually are not in conformity with Mt. 28:19 which commands Christians to teach all nations, not all creatures.
Also, going from house to house to preach is outdated in the presence of modern means of mass communication that will reach thousands of people at a time.
