Ultimately, the persistence and growth throughout history of the largest movement the world has ever seen is the strongest evidence for the resurrection. Many millions of people have claimed that their lives have been transformed by Jesus and that they had a relationship with Jesus. Even today, testimonies of lives that have been changed continue to flabbergast the skeptic and give more faith to the believer.
According to Robert Stein:
[Another] witness to the resurrection is the existential experience of the risen Christ in the heart of the believer. As one familiar hymn states it, “You ask me how I know He lives? He lives within my heart.” To those who would minimize this argument and reject it as unscientific and subjective, the evangelical would point out that millions of Christians have for nearly two thousand years made this very claim. It is a simple fact that throughout the history of the church, the single most important witness to the resurrection of Jesus has been the witness of the risen Christ within the heart of the believer!
