The resurrection of Jesus is the Christian belief that God raised Jesus on the third day after his crucifixion, starting – or restoring – his exalted life as Christ and Lord. According to the New Testament writings he was firstborn from the dead, ushering in the Kingdom of God. He appeared to his disciples, calling the apostles to the Great Commission of proclaiming the Gospel of eternal salvation through his death and resurrection, and ascended to Heaven.
For the Christian tradition, the bodily resurrection was the restoration to life of a transformed body powered by spirit, as described by Paul and the Gospel authors, that led to the establishment of Christianity. For Christians, his resurrection is the guarantee that all the Christian dead will be resurrected at Christ's parousia (second coming). In Christian theology, the death and resurrection of Jesus are the most important events, the foundation of the Christian faith, as commemorated by Easter.
