In that day, saith the Lord of hosts, will I take thee, O Zerubbabel, my servant, the son of Shealtiel, saith the Lord, and will make thee as a signet: for I have chosen thee, saith the Lord of hosts. Haggai 2:23. OHC 322.1
Christians are Christ's jewels. They are to shine brightly for Him, shedding forth the light of His loveliness. Their luster depends on the polishing they receive. They may choose to be polished or to remain unpolished. But everyone who is pronounced worthy of a place in the Lord's temple must submit to the polishing process. Without the polishing that the Lord gives they can reflect no more light than a common pebble. OHC 322.2
Christ says to man, “You are mine. I have bought you. You are now only a rough stone, but if you will place yourself in my hands, I will polish you, and the luster with which you shall shine will bring honor to My name. No man shall pluck you out of My hand. I will make you My peculiar treasure. On My coronation day, you will be a jewel in My crown of rejoicing.” OHC 322.3
The divine Worker spends little time on worthless material. Only the precious jewels does He polish after the similitude of a palace, cutting away all the rough edges. This process is severe and trying; it hurts human pride. Christ cuts deep into the experience that man in his self-sufficiency has regarded as complete, and takes away self-uplifting from the character. He cuts away the surplus surface, and putting the stone to the polishing wheel, presses it close, that all roughness may be worn away. Then, holding the jewel up to the light, the Master sees in it a reflection of Himself, and He pronounces it worthy of a place in His casket. “In that day, saith the Lord of hosts, will I take thee, ... and will make thee as a signet: for I have chosen thee, saith the Lord of hosts.” Blessed be the experience, however severe, that gives new value to the stone, and causes it to shine with living brightness.18SDA Bible Commentary 4:1177. OHC 322.4
God will not suffer one of His truehearted workers to be left alone to struggle against great odds and be overcome. He preserves as a precious jewel every one whose life is hid with Christ in God.19Testimonies for the Church 7:67. OHC 322.5
