Christians believe that Jesus is the Messiah (Christ) and believe that through his death and resurrection, humans can be reconciled to God and thereby are offered salvation and the promise of eternal life. These teachings emphasize that as the willing Lamb of God, Jesus chose to suffer on the cross at Calvary as a sign of his full obedience to the will of the Eternal Father, as an "agent and servant of God". The choice Jesus made thus counter-positions him as a new man of morality and obedience, in contrast to Adam's disobedience.
Most Christians believe that Jesus was both human and divine—the Son of God. While there has been theological debate over the nature of Jesus, Trinitarian Christians believe that Jesus is the Logos, God incarnate, God the Son, and "true God and true man"—both fully divine and fully human. Jesus, having become fully human in all respects, suffered the pains and temptations of a mortal man, yet he did not sin. As fully God, he defeated death and rose to life again. According to the Bible, God raised him from the dead. He ascended to heaven to sit at the Right Hand of God, and he will return to earth again for the Last Judgment and the establishment of the Kingdom of God in the World to Come.
