It amazes me that a group of people (which seems to be about 15 adults and 12 children) could build a temple by 560 BC like Solomon s Temple.(2nd Nephi) When it took Solomon the following: 180,600 people to build his -7 years. 70,000 were the people who carried the materials, 30,000 to move the cedars to the site, 80,000 to quarry the stones, and 3000 supervisors. Remember there were even fewer than the original number because Nephi and his group broke away from Laman and Lemuel s.
Another problem, The Holy Spirit was not given until Jesus was glorified (resurrection and ascension) John 7: 39 The Book of Mormon has people being slain in the spirit and speaking in tongues long before Jesus crucifixion.Alma.
One more problem: Zenos should have known that Olive Trees grow in a "grove" not a Vineyard.
Read the letters of Paul and find out the real inheritance Jesus has already won for you! It will change your life.
God loves us all. There is no partiality in Him. God Bless You in your life!
