He will wipe away every tear from their eyes; and there will no longer be any death; Revelations 21:4
This passage includes a vision Apostle John saw of a new heaven and earth in New Jerusalem in which God Himself declares that He will wipe every tear from our eyes. This New Jerusalem came down from heaven was described as a bride beautifully dressed for her groom. The Groom is the Christ and the Bride is the believers who have been born again by faith through Christ Jesus. The believers in New Jerusalem have been prepared for by Christ.
John declares from his vision that in this New Jerusalem God shall wipe away all tears from our eyes and that there shall be no more death, sorrow, crying and pain for the old things have passed away. This is the greatest thing to look forward to as believers that love God who called according to His purpose. As it says in Romans 8:18 that our present sufferings are not worth comparing with the glory that will be revealed in us.
