Session of Christ in the context of "Kingdom of God (Christianity)"

In Christianity, Jesus is the Son of God as chronicled in the Bible's New Testament, as well as prophesied in the Old Testament, and is held to be God the Son, a prosopon (Person) of the Trinity of God. Christians believe him to be the Jewish messiah (giving him the title Christ), who was prophesied in the Bible's Old Testament. Through Jesus's crucifixion and resurrection, Christians believe that God offers humans salvation and eternal life, with Jesus's death atoning for all sin.

These teachings emphasize that as the Lamb of God, Jesus chose to suffer nailed to the cross at Calvary as a sign of his obedience to the will of God, as an "agent and servant of God". Jesus's choice positions him as a man of obedience, in contrast to Adam's disobedience. According to the New Testament, after God raised him from the dead, Jesus ascended to heaven to sit at the right hand of God the Father, with his followers awaiting his return to Earth and God's subsequent Last Judgement.

The resurrection of Jesus (Biblical Greek: ἀνάστασις τοῦ Ἰησοῦ, romanized: anástasis toú Iēsoú) is the Christian belief that God raised Jesus from the dead on the third day after his crucifixion, starting—or restoring—his exalted life as Christ and Lord. According to the New Testament writing, Jesus was firstborn from the dead, ushering in the Kingdom of God. He appeared to his disciples, calling the apostles to the Great Commission of forgiving sin and baptizing repenters, 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. In Christian theology, the resurrection of Jesus is "the central mystery of the Christian faith." It provides the foundation for that faith, as commemorated by Easter, along with Jesus's life, death and sayings. For Christians, his resurrection is the guarantee that all the Christian dead will be resurrected at Christ's parousia (second coming). The resurrection is seen as a theological affirmation that intersects with history as a precondition for understanding the historical Jesus, his suffering, and vindication.

Christology is a branch of Christian theology that concerns Jesus. Different denominations have different opinions on questions such as whether Jesus was human, divine, or both, and as a messiah what his role would be in the freeing of the Jewish people from foreign rulers or in the prophesied Kingdom of God, and in the salvation from what would otherwise be the consequences of sin.

The earliest Christian writings gave several titles to Jesus, such as Son of Man, Son of God, Messiah, and Kyrios, which were all derived from Hebrew scripture. These terms centered around two opposing themes, namely "Jesus as a preexistent figure who becomes human and then returns to God", versus adoptionism—the idea that Jesus was a human who was "adopted" by God at his baptism, crucifixion, or resurrection. Prior to 2007, the scholarly consensus was that the divinity of Christ was a later development, though most scholars now argue that a high Christology existed prior to Paul.

God the Son (Greek: Θεὸς ὁ Υἱός, Latin: Deus Filius) or God the Word (Greek: Θεὸς ὁ Λόγος, Latin: Deus Verbum) is the second Person of the Trinity in Christian theology. According to mainstream Christian doctrine, God the Son, in the form of Jesus Christ, is the incarnation of the eternal, pre-existent divine Logos (Koine Greek for "word") through whom all things were created. Although the precise term "God the Son" does not appear in the Bible, it serves as a theological designation expressing the understanding of Jesus as a part of the Trinity, distinct yet united in essence with God the Father and God the Holy Spirit (the first and third Persons of the Trinity respectively).

The Ascension of Jesus (anglicized from the Vulgate Latin: ascensio Iesu, lit. 'ascent of Jesus') is the Christian and Islamic belief that Jesus ascended to Heaven. Christian doctrine, as reflected in the major Christian creeds and confessional statements, holds that Jesus ascended after his resurrection, where he was exalted as Lord and Christ, sitting at the right hand of God. Islamic doctrine holds that Jesus directly ascended to heaven without dying or resurrecting.

The Gospels and other New Testament writings imply resurrection and exaltation as a single event. The ascension is "more assumed than described", and only Luke and Acts contain direct accounts of it, but with different chronologies.

In Christianity, heaven is traditionally the location of the throne of God and the angels of God, and in most forms of Christianity it is the abode of the righteous dead in the afterlife. In some Christian denominations it is understood as a temporary stage before the resurrection of the dead and the saints' return to the New Earth.

In the Book of Acts, the resurrected Jesus ascends to heaven where, as the Nicene Creed states, he now sits at the right hand of God and will return to earth in the Second Coming. According to Catholic, Eastern Orthodox, and Oriental Orthodox teaching, Mary, mother of Jesus, is said to have been assumed into heaven without the corruption of her earthly body; she is venerated as Queen of Heaven.
