Answer:
I think there are still Roman Catholic Church and other Christian Churches because apostles are not the only people who heard the word of God there are other thousands who heard it. And there is a possibility that those thousands will have the courage and will preach the gospel around the world and Christian Churches will be built. Also our God will not let that happen because he wants all of us to be saved that's why he sacrifice himself to the cross.
Of course, I'm willing to sacrifice myself for the sake of my faith to God because our body here in earth will not live eternally but if I will sacrifice myself for God there is a possibility that I will possess the eternal body in heaven and in heaven there are no more sacrifices that we should make because in there we will experience only happiness and no more sorrows.
