Mosiah 15:16 - 15:20

Mosiah 15:16 And again, how beautiful upon the mountains are the feet of those that are still publishing peace!

Even how marvelous are those who are doing it now.

Mosiah 15:17 And again, how beautiful upon the mountains are the feet of those who shall hereafter publish peace, yea, from this time henceforth and forever!

And included are those who will come in the future to do the same things.
[Indication that there will always be prophets around and that they will not cease to exist regardless of what the righteousness of the people.]

Mosiah 15:18 And behold, I say unto you, this is not all. For O how beautiful upon the mountains are the feet of him that bringeth good tidings, that is the founder of peace, yea, even the Lord, who has redeemed his people; yea, him who has granted salvation unto his people;

And even more wonderful is the Lord who will bring salvation to all mankind by redeeming them from the fall.

Mosiah 15:19 For were it not for the redemption which he hath made for his people, which was prepared from the foundation of the world, I say unto you, were it not for this, all mankind must have perished.

Otherwise if He had not done this, we would have all been denied the chance to return to the Father if it was our desire.

Mosiah 15:20 But behold, the bands of death shall be broken, and the Son reigneth, and hath power over the dead; therefore, he bringeth to pass the resurrection of the dead.

But the plan of redemption is in place, Christ is in charge of the events of this world and has power to resurrect us all.
