Compare Malachi 3.
The Savior also told them to write the words of Malachi, and He taught them what these scriptures meant (verse 1).
Behold, I will send my messenger, and he shall prepare the way before me, and the Lord whom ye seek shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in; behold, he shall come.
Who can stand it when the Lord returns (verse 2)?
Those prepared by being at-one with Him, so that the “refiner’s fire” only purifies, instead of destroying (verse 3). We prepare by being righteous as He is righteous, and we can only be righteous by being at-one with Him. Except we cannot be righteous, not on our own. So this is the Great Exchange, that we offer Him a “broken heart and contrite spirit” (Psalm 34:18; Psalm 51:17; 2 Nephi 2:7; 3 Nephi 9:20; and D&C 59:8) as our “pleasant offering (verse 4), and then He offers us His righteousness.
If we are His people, we have nothing to fear. But there is more to fear if we are not following His law (verse 5), for He does not change and their are penalties for failing to keep our covenants (verse 6).
We must repent, and keep our covenants by doing what He says (verse 7). It affects everything. Breaking the laws of God affects everything and everyone around us. He gives the example of us robbing God by failing to pay tithes and offerings (verse 8), and how this brings a curse on all the people (verse 9). We must pay our tithes, for example, even to try it out and see that He will keep His promise and bless us for doing so. This is the law, and He is bound by the same law as we are.
Bring ye all the tithes into the storehouse, that there may be meat in my house; and prove me now herewith, saith the Lord of Hosts, if I will not open you the windows of heaven, and pour out a blessing that there shall not be room enough to receive it (verse 10).
Part of this blessing is that the devourer will be rebuked, and that the land will have what it needs, both in nourishment and protection, for vegetables and fruits and flowers to grow (verse 11).
All will know we are blessed, He says (verse 12).
But our words testify against us, if we are not testify of Him (verse 13). If we have declared our covenants, but do not keep them, our own words will testify against us (instead of our words testifying for Him). We cannot complain about ordinances or be sad about covenant-keeping (verse 14), or pursue false joys and illusions of happiness through doing wicked things (verse 15). Instead, we should remind each other of our covenants, and write our records of what the Lord has done for us, and think about who He is (verse 16).
Then we shall be His people (verse 17).
And He will know who are His people, and who are not. He will know who is righteous and who is wicked. He will know who serves Him and who does not. He will know His people (verse 18).
