The apostle John declared that God's righteous people who were living when Christ returned to earth would be those “which came out of great tribulation, and have washed their robes (characters), and made them white in the blood of the Lamb.” Revelation 7:14.
Mtume Yohana alitangaza kuwa watu wenye haki wa Mungu ambao wangekuwa wanaishi wakati Kristo anaporejea duniani wangekuwa wale “wanaotoka katika dhiki ile iliyo kuu, nao wamefua mavazi yao, na kuyafanya meupe katika damu ya Mwana-Kondoo.” Ufunuo 7:14.
