Verse 6 is a very unusual statement if left to itself, for it would appear to be negatively stated. The negative referencing of verse six is expanded into its positive conclusion in verse 7, and the two verses should therefore be read together, and they use the series of negations to significantly underline the closing positive line and declaration; "but there is a God, and he is Christ, and he cometh in the fulness of his own time."
As noted before, Nephi does make a distinction between Christ and the Father, yet understands Christ in his most powerful guise. Nephi understands an already risen Savior from his vision, and therefore sees the Savior in the eternal, not temporal setting. In Nephi's visionary understanding, he sees the resurrected and triumphant Savior in his position of glory.
