Jesus Christ is the only begotten Son of God, who was made the atonement for the sins of man. Being Holy and blameless he was humiliated, mocked, mutilated and subsequently, executed.
Three days after his death, He was resurrected by God and ascended to heaven.

If you confess with your tongue that Jesus is Lord and if you believe with your heart that God raised Him from the dead, you will be saved.
(Romans 10:9)
