The prophet and war captain Mormon of the Nephite nation was the national archivist, divinely-inspired compiler and commentator of what we have now as the Book of Mormon. He specifically saw our day and gave his advice to us through the lens of his people's historic and religious records. It is not just a story of the Nephites and Lamanites, their bitter brethren - it is more a guidebook to our times and how God deals with people and their behaviors.
Chapter Seven of his personal record is the "final words" that this historian gives, mostly to his surviving people, but also to we "Gentiles" which will be brought to God's set-aside land of the Americas.
Mormon speaks to all the descendants of Lehi, of which he was also one. Everything he promises for his own people is also promised to all of us as we make covenants with the Lord.
And ye will also know that ye are a remnant of the seed of Jacob; therefore ye are numbered among the people of the first covenant; and if it so be that ye believe in Christ, and are baptized, first with water, then with fire and with the Holy Ghost, following the example of our Savior, according to that which he hath commanded us, it shall be well with you in the day of judgment. Amen.
This is yet another statement of the importance of having an authoritative baptism. It really has to do with the authority of the person who does your baptism - it can't be just anyone. It has to be someone that Christ accepts as a priest, so you must figure that out. I am confident in myself that a priest in good standing of the Church of Jesus Christ of Latter-day Saints is authorized by Christ, but you need to determine that yourself.
The last recorded thought of Mormon is on "judgement" and how we will fare during it. I can't think of the last time anyone framed their afterlife in terms of doing well in the coming judgement rather than how wonderful Jesus is, as if that fact will just eliminate judgement entirely.
I think we all need to be concerned with "following the example of our Savior" - our actions in relation to God, our families, and others. "...that which he hath commanded us..." will be the things by which we will be judged for our ultimate reward. If we concern ourselves with following Christ and keeping his commandments, "it shall be well with you in the day of judgment." Easy enough for me to understand!
