Nephi's new guide is an angel. The angel serves the same guide role as the Spirit. It is interesting that the didactive method of both of Nephi's spirit guides was that of asking questions. In at least this one way, the revelation to Nephi required his active participation and working out of understanding. Nephi is also required to participate in the process rather than having the information "poured" into his head. Nephi, even in glorious vision, retains his agency which must be used to form understanding from what he is being shown.
