Isaiah 35

As Isaiah speaks of the blessings that will follow the restoration of the gospel for the righteous, he prophecies that -

"...an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein."  (Isaiah 35:8)

In my mind, "The way of holiness" is the gospel of Jesus Christ as I read this morning -

"Now this is the commandment: Repent, all ye ends of the earth, and come unto me and be baptized in my name, that ye may be sanctified by the reception of the Holy Ghost, that ye may stand spotless before me at the last day.
21 Verily, verily, I say unto you, this is my gospel; and ye know the things that ye must do in my church; for the works which ye have seen me do that shall ye also do; for that which ye have seen me do even that shall ye do;
22 Therefore, if ye do these things blessed are ye, for ye shall be lifted up at the last day."  (3 Nephi 27:20–22)
