In the end of chapter 21 the Lord is teaching the Nephites about hw he will establish His church in the latter days and gather the people in. Here in chapter 22 the Lord quotes Isaiah to give us a commandment to enlarge our tent's and strengthen our cords...which is confusing. But when you consider that the Lord was just talking about establishing His church and gathering people to it, it becomes clear that the Savior is giving us a charge to make room for all in His kingdom. To love, to bless and to welcome all who should enter in.
