Will racially prejudice people be accepted into God's kingdom?

"After these things I saw, and, look! a great crowd, which no man was able to number, out of all nations and tribes and peoples and tongues, standing before the throne and before the Lamb, dressed in white robes; and there were palm branches in their hands. 10 And they keep on crying with a loud voice, saying: “Salvation [we owe] to our God, who is seated on the throne, and to the Lamb.”
... “These are the ones that come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb. 15 That is why they are before the throne of God; and they are rendering him sacred service day and night in his temple and the One seated on the throne will spread his tent over them. 16 They will hunger no more nor thirst anymore, neither will the sun beat down upon them nor any scorching heat, 17 because the Lamb, who is in the midst of the throne, will shepherd them, and will guide them to fountains of waters of life. And God will wipe out every tear from their eyes." Rv7:9
