3 Nephi 24

The Savior wanted to make sure that the Nephites had the words of Malachi. Why?

2 But who may abide the day of his coming, and who shall stand when he appeareth? For he is like a refiner’s fire, and like fuller’s soap.
3 And he shall sit as a refiner and purifier of silver; and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the Lord an offering in righteousness.

The call to prepare to meet God is stated beautifully here. In the refining process, the silvermaker uses heat to burn away impurities until the silver is pure. As we experience trials and tests of our faith, the dross is gradually refined away until our faith in Jesus Christ is pure. We no longer need to look at others who disregard His will and think as some have:

14 Ye have said: It is vain to serve God, and what doth it profit that we have kept his ordinances and that we have walked mournfully before the Lord of Hosts?
15 And now we call the proud happy; yea, they that work wickedness are set up; yea, they that tempt God are even delivered.

We know and trust that by living in peace now according to His teachings, we are preparing for an eternity where God can make us His and bring us home to be with those we love.
