144,000 are a mere drop in the ocean compared to this great number. People may be surprised to learn that the numbers have still not been completed, because they do not realize how valuable each of the 144,000 is. The people included in the 144,000 are mostly martyrs. They were not killed by accident during the persecution of Christians, but were righteous persons who were willing to abandon their life to keep their faith.
The people who become the bride of the Lamb by their pain and death will receive tremendous authority in the spiritual world after the spiritual war. They will receive the authority to judge all people from the beginning of humanity and the authority to be kings and high priests (Rev. 20:4-6). It is not easy to be included in the number.
The value of a single righteous person is so huge that God would have forgiven the sins of all the people in Jerusalem if he had found one amongst them (Jer. 5:1). God knows that he will be able to destroy the power of Satan, which is like the sand on the seashore, with only 144,000 righteous people. Therefore, we can assume how strong the person who possesses the light of God would be.
