I am going to give you a lesson in math.  Rather than put you to sleep, I think that it will be eye opening.

I'm going to center my remarks around the word "multiplicity."  Multiplicity means "a great number."  It might also mean "innumerable."  The word is used just once in scripture.  In D&C 104:42 the Lord says, "I will multiply blessings upon him ... even a multiplicity of blessings."  I'm enchanted with that word and its implications.

A similar statement is made in 4 Nephi 1:11 where it is reported that "they ... were blessed according to the multitude of the promises which the Lord had made unto them."

A "multiplicity of blessings" and a "multitude of promises."  What are they?  Who gets them?  How can you and I qualify for these innumerable blessings and promises?

It has to do with the dispensation of Abraham.  Anyone who embraces the gospel of Jesus Christ through baptism and the making and keeping of covenants becomes a recipient of the promises and blessings given to Abraham.  That person becomes Abraham's seed.

Abraham sought and received the Priesthood, the authority to act in the name of God.  There is no authority that exceeds that authority.  No earthly authority can do the things that the Priesthood of God can do.  The Priesthood of God can still storms, raise the dead, heal the sick, and make stones shine in darkness.  Even more wonderfully it can seal families together eternally.  It can baptize and bring about a complete erasure of sins.

The Priesthood of God is the greatest power on earth.  It is more powerful than a cyclone, or gravity, or disease, or death itself. --And Abraham got to hold it.  Abraham got to use it.  Abraham was promised that his faithful seed would have and use the Priesthood, also.

That's you and me.  We use the Priesthood to baptize and to remit a person's sins.  We use the Priesthood to give the baptized person the continual companionship of a member of the Godhead following his baptism.  The Priesthood binds us to Jesus Christ, and binds us together as families.

The Priesthood is a huge blessing.  It was promised to us before we were born.  (Alma 13:1-9).   Because of that promise we were born into conditions where we would receive the Priesthood in mortality.

The blessing is huge.  We must not take this promise and this blessing lightly.  We must not take it for granted.  We must continually be worthy of and thankful for this trust.

Abraham was promised that his posterity would be as numerous as the stars in heaven, or as the sands upon the seashore.  (Genesis 22:17-18)  As his posterity, that same promise is ours.

Abraham's daughter-in-law, Rebekah, received her patriarchal blessing in which she was told that she would become the mother of "thousands of millions."  (There's another mathematical term).  (Genesis 24:60).  One thousand million is one billion.  "Thousands of millions" is at least two billion.  If Rebekah's two boys each had five children, (they each had a dozen) and if each of them had five children, and if that continued down to the present day, Rebekah's posterity now numbers well over two billion people.

You and I are Rebekah's posterity.  We are Abraham's posterity.  Their promises and blessings are our promises and blessings.  Your posterity will one day be as numerous as the stars in heaven or as numerous as the sands upon the seashore.

God said that "worlds without number have I created."  (Moses 1:33 and 35).  That's a multiplicity of worlds.  There is also a multiplicity of God's children upon each of those innumerable worlds.

Our promise and blessing is that, if we live for it, we are to become like God.  The promise is that we are to become creators of worlds where we will place our children so that they can have their own mortal experiences.

These numbers, promises, and blessings are beyond our comprehension.  What we do really does matter.  What we do will matter to a multiplicity of people.  Their eternal happiness and destiny rest upon the hold that we have upon ourselves, and upon our faithfulness.

Beyond that, let us consider the multiplicity of promises and blessings that are ours here on earth in our mortality.  If we are faithful to our covenants we are promised peace in the midst of turmoil.  We are told to seek and to expect miracles.  (Russell M. Nelson, General Conference, April 2022).  We are promised guidance in our decisions.  We are promised that if we faithfully have Family Home Evenings that our children will not go astray.  We are promised "health in (our) navel and marrow to (our) bones."  (D&C 89:18-21).  Marrow in the bones will become a huge blessing if we are ever confronted with the problem of having to deal with nuclear fallout.

We have scripture.  We have more scripture than any people on earth have ever had.  We have the promise of more to come.  We have prophets to lead and guide us.  We have penicillin, electricity, and running water.  No king in any past dispensation dared to dream of such luxury.

Through our faithfulness, we have the ability to bless the lives of posterity not yet born.  Still more remarkably, we have the ability to bless the lives of our ancestors of every generation.

Before we were born we made promises with all of these people.  With some we made covenants that if they would come when times were hard, and when gospel ordinances and covenants would not be available, that we would see to it that they could receive them through our vicarious work.  With others we made covenants that we would prepare a home and an environment where they could come and partake of every promise and blessing available to the faithful.

All of these people are not far from us and know of our circumstances and of our ability to bless their lives.  They are praying for us.

That's a sobering thought:  They are praying for our success and for our worthiness.  Their salvation depends upon us.

What I do really does matter.  It matters to a multitude of people.  (That means numerous and innumerable).

What I do will determine whether they, and I, will receive this multiplicity of promises and blessings, or just a handful.

Do the math.  You can have a handful of blessings or a multiplicity of blessings. The choice is ours.  The way isn't hard.  It's doable, and so very worthwhile.
