Revelation 11:3-10 powerfully attests to the biblical importance of burial:
Revelation 11:3 And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. 4 These are the two olive trees, and the two candlesticks standing before the God of the earth. 5 And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed. 6 These have power to shut heaven, that it rain not in the days of their prophecy: and have power over waters to turn them to blood, and to smite the earth with all plagues, as often as they will.
7 And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them. 8 And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified.
9 And they of the people and kindreds and tongues and nations shall see their dead bodies three days and an half, and shall not suffer their dead bodies to be put in graves. 10 And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.
During the cataclysmic event of the last days, God will direct two witnesses who will prophesy in a unique ministry lasting for 1260 days. These two witnesses will engage in a miraculous ministry that will bring great torment to the whole world.
When they have accomplished their God-given mission, the beast that will arise from the bottomless pit will slay them. The world will rejoice greatly at their demise and will not permit their dead bodies to be buried.
Three and a half days after their deaths, God will miraculously raise them from the dead and then cause them to ascend up into heaven while their enemies watch (Rev. 11:11-12).
Although these witnesses will die in Jerusalem (cf. 11:8, “where our Lord was crucified”), the Spirit does not explicitly say that they are Jewish people. Yet, the Spirit highlights that the world will not allow them to be buried.
By doing so, the Spirit highlights in a profound way that burial will continue to be the will of God for His servants regardless of how far removed in time from biblical times their deaths take place! He also teaches us that He wants His people buried after their deaths even when the entire world stands in opposition to their being buried.
Burial is an important part of the testimony of believers to a world that stands in opposition to God. God’s people should not have anything to do with the unbiblical practice of cremation. They should bury their own whenever they have any say in what happens to His people after they die!
