Apparently, this is going to happen quickly - within the lifetime of the servants. The wild branches, representing the Gentiles, will be cut down and cast into the fire. This is similar to what happened to the Nephites at the end - when they went contrary to the commandments which Jesus gave them in the Sermon, they, too, were hewn down and cast into the fire quickly. We are looking at the Gentiles being swept off as dew before the sun, because they will not keep the commandments of the Lord as given in the Sermon.
Hope lies in repenting of disbelief in the words of Jesus Christ and putting his commandments as given in the Sermon into continual and literal practice, praying always against temptation, and teaching our children to do likewise.
Nothing else matters.
