"He will swallow up death in victory; and the Lord GOD will wipe away tears from off all faces; and the rebuke of His people shall He take away from off all the earth: for the LORD hath spoken it" (Isaiah 25:8).
It may be surprising to learn there are tears in heaven, but there are three places in the Bible where we are told that God will wipe away our tears there. This promise appears first in the Old Testament, in our text--a text which is quoted in the New Testament as applying to the events of the second coming of Christ. "Death is swallowed up in victory. O death, where is thy sting? O grave, where is thy victory?" (I Cor-inthians 15:54-55). The graves will be emptied and death itself will die when Christ comes again! But there will still be those tears, even after death, which God must wipe away.
The other two occurrences are in the last book of the Bible, both again in the context of the return of Christ. "|Who| . . . shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes." Finally, in the new Jerusalem, "God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away" (Revelation 7:17; 21:4).
But why should there be tears at all when death has passed away? The Scriptures do not say specifically why, but it seems probable that these may be tears of regret at lost opportunities, and tears of sorrow for unsaved friends and loved ones. It does say that, in the new earth, we shall somehow "look upon" the lost (Isaiah 66:22, 24) and that even some of the saved "shall suffer loss" when their works in this life do not "abide" in the judgment (I Corinthians 3:13-15). But then, after these tears are shed, God will graciously wipe them away, and there will never be sorrow or crying any more. HMM
